I can sympathize with the desire to want the days of desktops and executable games to linger. I too find it difficult to understand how gaming has changed so much in only a few years. The reality is we are moving away from powerful, full tower desktops towards terminals whose only purpose is to connect to a server.
I�ve thought on many occasions that if the EDK were available I would write an Android exporter and sell it. However, I doubt anyone would buy. HTML5, especially with WebGL, will run very fast on mobile devices - if not today, someday very soon. Who would pay for it when they can just use the included HTML5 exporter for free? It isn�t worth my time or Ashley�s time to write an exporter.
C2 is being built on a gamble: that HTML5 and WebGL are the future. Early adopters are sharing in that gamble. If you can�t see a day when web technologies will dominate or at least be an important part of the gaming industry, then C2 is not a good choice.
Lastly, if you truly need so much power that you must target the CPU and GPU directly, learning C or C++ and OpenGL or DirectX is really your only option. However, I can�t even imagine a 2D game that needs that much power. All of my favourite 2D games ran on the SNES with its beefy 21.5 MHz CPU.
