This is a game under heavy development and commits might not be explained etc. Use/fork at your own risk!
Developed using faiface/pixel 2D library (https://github.com/faiface/pixel).
The Pixel commit below is the latest (currently) and contains a patch I've added for supporting export of vPosition between vertex and fragment shader and is needed by this game.
