Been thinking about joining and participating in this.
Just think about it: tracked music, small game size, 2 player support, fancy VFX....
No chance of a Mac port, even though I will be using BASS and OpenGL, which do work on Macs. I know it will not be the caliber of Plasma Pong, which was in devel for around 9 months, but fuck it. I WILL have fun developing this.
