Nothing much fancy about it, ColbaKing is just a regular old school javascript game (more like a clone of Chrome's dino-game).
Uses basic javascript's requestAnimation method to manipulate HTML5 canvas.
Game controls are simple. In pc, use spacebar or W for jumping and H for make the king laugh (not important though). In touch screen devices, all you have to do is tap the screen again and again (No laughing option here :).
