So the big day is finally here! The moment we have been working on since we decided to bring our little [Chrome extension / Web game](https://battletabs.com/) to mobile some 2 years ago.

We have finally made the game globally available on both iOS and Android!

If you are interested in a little more detail about the history of the game and where that funny name comes from then you can check out [another video we put together here](https://mikecann.blog/posts/battletabs-in-7-minutes).

# Since Soft Launch

Over 6 months ago [we announced](https://mikecann.blog/posts/battletabs-enters-soft-launch) we were entering Soft Launch for mobile. Since then we have been iterating, adding features, tweaking features and fixing bugs. Things have taken a little more time than expected mainly because we decided to focus on our [Discord Activities launch](https://mikecann.blog/posts/battletabs-global-launch-on-discord-activities) which seemed like (and has been) a great opportunity for us.

With that behind us now we are back focused on mobile. The main priority has been performance and stability. One issue with building your mobile game using web technologies is that you unfortunately don't get as much control over resources such as GPU memory as you might do if you were going with a more native approach.

This means we have been at the whim of whatever browser technology is available on the platform. In the case of iOS this means WebKit. It has been known for a while now that WebKit on iOS isn't great, conspiracy theorists would say this is because Apple is intentionally trying to hobble web experiences on mobile in an effort to boost App Store sales. I don't know, all I know is that we have had a bit of a hard time with GPU memory crashes on iOS mobile.

These crashes can happen at just about any point in the game which makes it really tricky to replicate and thus debug the problem. The tooling that Apple provides (only available on Macs of course) isn't great and unfortunately crashes all the time when we try to use it.

We have narrowed down the bulk of the crashing is related to [browser layering](https://medium.com/masmovil-engineering/layers-layers-layers-be-careful-6838d59c07fa) particularly when combined with CSS animated elements. This seems to force a high GPU memory usage as WebKit attempts to hardware accelerate large layers.

Curiously Chrome (and thus Android) does not have this problem so I, as a Windows user, am not able to debug this problem from my PC.

We don't have a definitive solution for the problem, I suspect the issue is still there but we have tried our best to minimize it by removing most usages of CSS animations (on iOS) and changing the League Page over to a much simpler design as it was the culprit of many crashes.

# Apple Feature

A few weeks back we excitedly received an email from Apple informing us that we may be featured on the App Store.

[![](./app-feature.png)](./app-feature.png)

We submitted all the media information required so fingers crossed we do. Apple declined to comment on likelihood or timelines so we will see. If we do get a feature then it should hopefully be a big boost to game traffic. In preparation we have scaled up our servers just in case, I don't want another repeat of the [Discord Activities global launch](https://mikecann.blog/posts/battletabs-global-launch-on-discord-activities) ;)

*EDIT*: [We were indeed featured in the US](https://www.linkedin.com/feed/update/urn:li:activity:7258089646545334273/)!

# Conclusion

So it's been a long time in the making but we are super excited to have the game finally available to (just about) everyone's mobile device and tablet. I'm looking forward to battling with you guys from around the world soon!

Just a quick one and some good news on the nibbles front since the horror story that was my [Google Play debacle](https://www.mikecann.blog/misc/why-i-probably-wont-be-making-another-mobile-game-ever-again/).

My PC publisher for Mr Nibbles Forever and good friends over at [Black Shell Media](https://blackshellmedia.com/) have very kindly decided to publish the Android version of [Mr Nibbles Forever to the store](https://play.google.com/store/apps/details?id=com.blackshellmedia.mrnibblesforever). This is great news as the game I spent so long developing, working on and promoting is once again available for others to enjoy.



So I want to say a massive thankyou to Raghav and the others at [Black Shell Media](https://blackshellmedia.com/).

So what are you waiting for, [go download it now](https://play.google.com/store/apps/details?id=com.blackshellmedia.mrnibblesforever)!

The past couple of weeks I have been working on a new project and something a little different from my usual games related projects.



A few weeks ago a colleague in the office (TheBroth) mentioned an idea for an app but didn't have the time / energy to work on it so I thought I would have a stab at it.

The idea is simple. It lets you convert unused Google Play credit into cash.

[![1](https://www.mikecann.blog/wp-content/uploads/2016/03/1.png)](https://www.mikecann.blog/wp-content/uploads/2016/03/1.png)

It does it by allow the user to pick from a number of In-App-Purchases

[![2](https://www.mikecann.blog/wp-content/uploads/2016/03/2.png)](https://www.mikecann.blog/wp-content/uploads/2016/03/2.png)

They then supply their Paypal email address

[![3](https://www.mikecann.blog/wp-content/uploads/2016/03/3.png)](https://www.mikecann.blog/wp-content/uploads/2016/03/3.png)

I then simply send them some money via Paypal. Simples.

[![6](https://www.mikecann.blog/wp-content/uploads/2016/03/6.png)](https://www.mikecann.blog/wp-content/uploads/2016/03/6.png)

Im making 10% on each transaction with 30% going to Google and 5% to Paypal therefore the user gets 55% of their credit redeemed. Its not perfect but its better than nothing.

I made the whole thing in a couple of weeks of my part-time time. The Android app was made with React-Native using Typescript. I wrote a custom server using NodeJS (Typescript) on Heroku with a MongoDB data store. I wrote a custom Admin tool and website using React.

Due to the relatively small size of this app I would rather have used a MBaaS solution like Parse but as Parse just announced that they are discontinuing the service and I haven't found a good alternative just yet I thought I would bite the bullet and learn how to do it myself.

As usual I enjoyed the learning experience, there were definitely some teething pains, particularly around the Javascirpt / Typescript tooling and module loading issue but all in all im happy with the result.

If you are interested in checking it out, I have bought the domain here: [https://creditredeemer.com/](https://creditredeemer.com/) and the android app itself is here: [https://play.google.com/store/apps/details?id=com.creditredeemer](https://play.google.com/store/apps/details?id=com.creditredeemer)

Let me know what you think :)

The title says it all! The game is now finally out on Google Play:



[https://play.google.com/store/apps/details?id=uk.co.mikecann.mrnibblesforever](https://play.google.com/store/apps/details?id=uk.co.mikecann.mrnibblesforever)

It took me much longer than I had originally expected when I started it [back in January](https://www.mikecann.blog/portfolio/mr-nibbles-forever-a-prototype/) but im happy to say that no matter how it performs on the marketplace I feel as if I did it justice. I tried hard not to get fed up towards the end of the project as I tend to and put the hard graft in to get the monetisation and gameplay right.

I missed the deadline for the iOS version today as its still waiting to be approved by Apple but im hoping it wont be too much longer.

After that I plan on doing an Amazon build of the game and perhaps a content pack or two depending if I get more than just a handful of players :)

Well its been exactly [95 days since my last Alpha release](https://www.mikecann.blog/myprojects/mr-nibbles-forever/mr-nibbles-forever-alpha-7/) of my mobile game Mr Nibbles Forever which is far too long. I apologise to people who have been asking me for a new version. I took on a few paid freelance projects a few months ago and they took up a whole bunch of time then I decided to take a full time position up in Perth a month ago which [drastically cut down my Mr Nibbles development time](https://www.mikecann.blog/uncategorized/started-work-at-thebroth-in-perth/) sadly.



If you follow my [public Trello development board](https://trello.com/b/Ic11WQzF/mr-nibbles-forever) however you can see that I have been working in the intervening time, just not as fast as the earlier development:

[![2015-06-18_15-22-50](https://www.mikecann.blog/wp-content/uploads/2015/06/2015-06-18_15-22-50-1024x525.png)](https://www.mikecann.blog/wp-content/uploads/2015/06/2015-06-18_15-22-50.png)

In total there is something like 70 hours worth of my time that has gone into this release:

[![2015-06-18_15-21-12](https://www.mikecann.blog/wp-content/uploads/2015/06/2015-06-18_15-21-12.png)](https://www.mikecann.blog/wp-content/uploads/2015/06/2015-06-18_15-21-12.png)

Although 70 hours doesnt sound like all that much I think that this release contains more changes than any other. As hinted in the last release and other posts, I now have an artist on the project, [Woody Stables](https://twitter.com/woodystables) who has helped totally transform the in-game backgrounds, the outfits, the effects and many other aspects of the game:

[![2015-06-19_07-54-53](https://www.mikecann.blog/wp-content/uploads/2015/06/2015-06-19_07-54-53-1024x575.png)](https://www.mikecann.blog/wp-content/uploads/2015/06/2015-06-19_07-54-53.png)
[![2015-06-17_20-46-28](https://www.mikecann.blog/wp-content/uploads/2015/06/2015-06-17_20-46-28-1024x766.jpg)](https://www.mikecann.blog/wp-content/uploads/2015/06/2015-06-17_20-46-28.jpg)
[![2015-06-19_07-54-14](https://www.mikecann.blog/wp-content/uploads/2015/06/2015-06-19_07-54-14-1024x576.jpg)](https://www.mikecann.blog/wp-content/uploads/2015/06/2015-06-19_07-54-14.jpg)
[![2015-06-19_07-54-30](https://www.mikecann.blog/wp-content/uploads/2015/06/2015-06-19_07-54-30-1024x576.jpg)](https://www.mikecann.blog/wp-content/uploads/2015/06/2015-06-19_07-54-30.jpg)

So now there are 13 different outfits in the game which you can win by spinning the wheel. They all look different and awesome but still stick to the same cutesy Mr Nibbles art style. Some of them come with cool and interesting effects as the below video shows:

<iframe width="854" height="510" src="https://www.youtube.com/embed/aN5S0zMux30" frameborder="0" allowfullscreen></iframe>

You will also notice (if you have your sound turned on) that the game also now has a whole bunch more sound effects. That's entirely thanks to [Joe Watkins](https://twitter.com/watkinsonic) who I recruited to help out with the audio on the game. I think the audio really lifts the game up and adds so much more value to the different outfits and is often an overlooked but valuable part of games making.

The game really has started to take its final shape in my opinion but there is the problem. At the moment it has mostly only been my opinion of the game which has shaped its development. I have had a few testers play the game throughout its development and im very grateful for that but now its getting to the point where I need to test in earnest.

I am also very aware of the fact that I need to concentrate on marketing the game much more. At the moment the game is only really visible to a small number of people, people who read this blog, people who are members of the facebook page and people who I have met and talked to about the game. If I want the game to succeed and not get swallowed on the App Store then I need to step up my game in that department.

I have been doing a lot of reading about indie game marketing and have discovered [some valuable resources](https://vgamemarketing.com/). Its a massive daunting task but I have spoken to some other people who have done it and they have given me some great advice which has helped immensely.

So the next few weeks for me will be less about development and more about testing the game and building the things to help promote the game (websites, trailers, presskit etc).

If you would like to try the game out then as usual just [send me an email](mailto:mike.cann@gmail.com) if you are on iOS or [send a request to join this google group](https://plus.google.com/communities/100690884724496136044?gclid=CJSZo8WqgsACFVZwvAodlo0AHQ&dclid=CODB18WqgsACFVQZvAodWV4ATQ) if you are on Android and ill hook you up!

[![](/wp-content/uploads/2012/09/header.jpg "header")](/wp-content/uploads/2012/09/header.jpg)

Well its been a couple of weeks since we launched on iOS and a few weeks since Android, so I have decided to write one more post on the Mr Nibbles project. A post mortem into what went right, what went not so right which should hopefully serve to solidify my learning from the process and perhaps help others who should embark on something similar.



Before I dive into that, first some statistics thus far..

## Statistics

**Android**

[![](/wp-content/uploads/2012/09/2012-09-02_1250.png "2012-09-02_1250")](/wp-content/uploads/2012/09/2012-09-02_1250.png)

We have had 2,867 User installs and 1,623 active device installs. Not bad :)

**iOS**

[![](/wp-content/uploads/2012/09/2012-09-02_1252.png "2012-09-02_1252")](/wp-content/uploads/2012/09/2012-09-02_1252.png)

3,789 iOS installs, making a grand total of 6,656 mobile installs, not bad :)

## The Process

So from [the beginning](/posts/lets-make-a-mobile-game-in-3-weeks-with-haxe-nme/) the this project was to be a quick turn around project. The idea was to try and complete the whole thing in three weeks. It actually ended up being more like 5 weeks for me and 4 weeks for Moh the artist (he was on holiday for one of those) but still not months of development which I wanted to stay clear of.

For me, short time-scale games are so much more fun to make than long games. In a short time you can iterate quickly over the core idea then get it out there quickly and see what people think. When time constrained you are are forced to only implement the core functionality and discard the rest. In all likelihood the other stuff is probably just fluff anyways and not really necessary to the game.

As for the time-overrun, there is no one main reason for it. Lots of small things such as; unfamiliarity with NME / iOS / Android development, windows / osx development workflow and testing taking longer than expected. Making and testing each of the 30 levels took alot more time that I had anticipated. Working around some small NME issues (more on that below) took some time. Writing these blog posts every week (sometimes more) took some time out of what could have been development time too (more on blogging below).

The hours we worked on the project were actually okay. Because this was a personal project and both of us have full time jobs at [Playdemic](https://www.playdemic.com/) we could only work on the game during our evenings and weekends. During week days we tended to start about 6-6:30pm then work until we were kicked out of the office by the security guard. 8:30-ish usually. Occasionally (mostly towards the end of the project) we stayed a little later to get stuff done before release.

![](/wp-content/uploads/2012/09/testing.jpg "testing")

This sort of schedule and working pattern suited us both. Being able to see who you are working with and talking face to face I think really adds to the experience and fun of making an indie game. Its definitely more exiting to run over and show the other person some cool new level on your iPad rather than try to describe it over MSN from your bedroom. Working like this obviously wouldn't have been possible if the management at Playdemic weren't so awesome by allowing us to use the office after normal office hours so definitely a massive thanks there.

## Blogging

I strongly feel that blogging everything is one part of the process I definitely wouldn't change. Sometimes I choose to work in private on some projects however  this one I decided to be very public, announcing upfront the intent and regularly updating on progress. Blogging regularly and getting feedback on progress really encouraged me to stick with it every singe evening. It also served as a way to keep the project fun (absolutely critical for me) as the immediate feedback from people would serve as a basis for ideas and improvements.

Also writing things down has been proven to encourage stronger learning and memory retention, so hopefully in the future I wont make the same mistakes ;)

## Haxe + NME

I have been using [Haxe](https://haxe.org) for over a year now for various personal and professional projects so I was fairly familiar with the language going into this project. Haxe is a good language, similar to AS3 / ECMA based langues and so it shouldn't feel too alien to a seasoned flash developer. It does however come loaded with many improvements over AS3 such as proper generics, type inference, macros and many more awesome features.

[NME](https://haxenme.org) is a library built ontop of Haxe. It provides a familiar flash api but is able to many platforms natively. Using exactly the same Haxe code base I was able to compile Mr Nibbles to Flash, iOS, Android, Blackberry, Windows and OSX thanks to NME. The library really is great for this sort of fast-turn-around game. Mr Nibbles certainty wouldn't have been possible without it (not in 5-weeks anyways).

![](/wp-content/uploads/2012/09/testing2.jpg "testing2")The NME developers have put a lot of time into making the build and certification process as easy as possible for the various platforms. So with "nme setup android" from the command line for example you are able to download and setup the android SDKs and get your certs setup in the correct place for building. Its really great to see that sort of dedication to making the cross platform compilation process as smooth as possible.

The performance of NME is truly great. Thanks to its batched sprite rendering there are very few draw calls and expensive texture-switching. Mr Nibbles runs at solid frame rates on pretty much every smartphone you can think of from the Android G1to the Galaxy S III to the iPhone 3G to the iPad3\. After having worked with the[ nightmare that is J2ME mobile games](/posts/worms-2/) in the past, being able to run your game on so many devices without any code changes really is a pleasure.

NME isn't perfect however and does have a few issues such as slow and imperfect vector rendering from SWF files. It is however constantly constantly being worked on and im sure it wont be long before the issues are ironed out.

Because both NME, Haxe and most of the third-party libraries are open source you are always free to dive in and fix any issues yourself. For Mr Nibbles, the SWF rendering was "good enough", such that we were able to make nice looking menu screens that dynamically scaled to any device resolution and pixel density (a real time saver!). Most of the time when I ran into the issue I would post it on the NME mailing list. More often than not it would be answered (often by the NME-super-hero [Joshua Granick](https://www.joshuagranick.com)) within an hour or less!

## iOS

iOS was definitely the primary platform we were developing Mr Nibbles for. Mostly because it was the platform I owned a mobile and tablet device for ;) To develop for iOS you need to use osx and xcode, so I took my MBP into the office and hooked it up via Ethernet to the network. I setup a shared folder on my desktop machine and the pointed xcode on my MBP to that shared folder. That way whenever I made a change on my windows computer I would only have to hit one button in OSX to rebuild and test on my iOS device. It was a real time saver over the other approach I was previously using, syncing over Dropbox.

There were are few frustrating moments towards the end of the project when I was running into issues regarding ArmV6 and ArmV7 when NME was compiling. Fortunately I noticed in the [nmml spec](https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CCMQFjAA&url=http%3A%2F%2Fcode.google.com%2Fp%2Fnekonme%2Fsource%2Fbrowse%2Ftrunk%2Ftools%2Fcommand-line%2Fspec.nmml&ei=If9EUI7UN4ez0QWYkYHQCw&usg=AFQjCNEl3n-oz1tHz4ZPceTNYidpyTxolA) for NME there was an option to compile to "FAT" which seemed to make the issue to away ;)

## Android

Android was a lot easier to iterate and test because it could all be done from my desktop machine. In hindsight, and with the devices that only became available towards the end of the project, it would have been better if we had concentrated on the Android build first then ported to iOS later. Once we had some devices to test on however I was incredibly impressed with how easy it was to build and launch the game onto an Android device with NME. Literally just "nme test android" from the command line and it would compile and launch directly to the[![](/wp-content/uploads/2012/09/522085_10151008075505740_663326715_n-300x224.jpeg "522085_10151008075505740_663326715_n")](/wp-content/uploads/2012/09/522085_10151008075505740_663326715_n.jpeg) device, no faffing about.

Since launch there have been a few issues with audio crashing on Android. However I believe some people have been working on this so I may do a new build of Android in the near future and push an update of the game to the Google Play store.

## Blackberry

The blackberry build has only been finished very recently, hence the lack of stats thus far. It was actually really easy to build for Blackberry, again just a matter of changing a single word on the command line "nme rebuild blackberry" and that was it.

The hardest part was testing it as I had no Blackberry device to test on. Joshua Granick was extremely kind and offered to test the game out on his device. Not only that, he put in a kind word and managed to get a Playbook shipped out to me so I could test too, thanks Joshua :)

## Conclusion

Overall I had an absolute blast working on this game. Sure it was hard work, alot of evenings and weekend spent in the office till 9pm and sure it went over budget by two week but it doesnt matter because I was having fun the entire time.

This is what making games is all about for me, if you want to have fun programming I cant think of a better way than to make than to develop short-project games. Haxe with NME were instrumental in making the process as fun as possible by taking out much of the bull sh\*t with cross-platform development, letting you get down to business of turning your ideas into reality. So massive thanks to everyone that has worked on developing Haxe and NME.

Finally I want to say a massive thanks to my colleague and artist partner on this project Moh who's time and hard work made Mr Nibbles come alive, nice one Moh!

Finally! Apple approved the iOS version of the game this morning, and this evening I finished off the site, so the holy trinity of game availability; iOS, Android and the browser is now complete!

For once I actually finished one of my projects :) Im really happy with how the whole thing went, sure it went a couple of weeks over my original three-week estimate but still im happy with the result. Of course there is so much that could be improved, but for a free game made in a very short time I think it has done

Wow! This is pretty mental. I know a while back someone had managed to get a Linux kernel running on the iPhone, but there wasnt much to see and I soon forgot about it. It appears now however that [PlanetBeing ](https://linuxoniphone.blogspot.com/2010/04/ive-been-working-on-this-quietly-in.html)from the Dev-Team has managed to take an Android build and get it to run on the iPhone! Check out the video of it below:

Very cool stuff. I cant wait to see some Flash 10.1 running on that!
