Porting a HTML5 game: 6 platforms, 1 codebase.

That's a great idea for getting the most out of your dev efforts (and hitting the maximum number App Stores ;) - but do you end up with a lot of "conditional code"?<p>edit: ah, missed the internal link - it's explained in more detail: <a href="http://blog.greweb.fr/2011/06/automating-web-app-development-for-multiple-platforms/" rel="nofollow">http://blog.greweb.fr/2011/06/automating-web-app-development...</a>

If you are developing for iOS, you could also package your game with a more "native" wrapper, like my iOSImpact[1] instead of PhoneGap. This has better performance (OpenGL graphics instead of the browser view) and perfectly working sound with all the same source code as the web version.<p>[1] <a href="http://www.phoboslab.org/log/2011/04/ios-and-javascript-for-real-this-time" rel="nofollow">http://www.phoboslab.org/log/2011/04/ios-and-javascript-for-...</a>

I'm continusly impressed by the progress of Javascript recently and WebAppBuilder does look like it took a lot of hard work. BUT... quality cross-platform-automated-build-100-appstores-deployable unicorns are still fantasy. It might work for simple games, like the one in your example, but add a serious physics engine and sprites in there and too much creativity and such frameworks become more pain than help. Web is still high-level and hard to compete with platform specific optimizations and low-level APIs. Especially in a creative world like game development.<p>I have heard so many times friends/colleagues dreaming of apps which you write once and deploy it on everything. Can we please put a stop to these stories and take the time to build quality games, rather that get rich quick fart apps?

It's great to see a real-world writeup of cross-platform development using HTML5. One question: I tried the app on Android, and it looks pretty much identical to the web version, so -- success. However, the animations seem very slow and chunky -- I'm guessing less than 10/frames second, sometimes significantly less, even though the game is very simple visually. Is this an inherent limitation of HTML5 animations on Android? What about other mobile platforms (e.g. iOS)?

Well done. Surprising good fun to play !
