Caverns of Mimas
CM is the first of a series of mini-games. The game was released for the PC around the beginning of March 2012, a version for android devices was released by the end of March, and the OS X version was released in December.
Caverns of Mimas has its own homepage: http://www.cavernsofmimas.com/
The game engine is written in a highly portable subset of C, but the front-end is ported from platform to platform.
The PC version is written in C# and C++/CLI using XNA.
The android version is written in Java using JNI and OpenGL 1.1
The OS X version is written in Objective-C, Cocoa and OpenGL 2.0+.
The iOS version is written in Objective-C and OpenGL ES 2.0.
