Yeaaah, I made the mistake of saving the sound manager for last -- something happened when I tried to gate sounds so they don't overlap and I couldn't fix it before the submission :P. I was never able to finish the actual gameplay elements either - definitely more of a prototype at the moment.
Thanks! I'm new to Blender, but once I found a good workflow it was much easier to use (and after watching some tutorials:
The grid is made from a world space shader and I used a custom render target to lower the resolution of the game but not the UI, as well as apply some post-processing effects like vignetting and dithering.
GLSL shaders are great!
