Dynamate is a game originally made by Björn Kalzen and Jonas Norberg. It is a puzzle game where you have to try to remove colored pieces from the playfield by letting them collide with another specific colored piece. There are pieces that are stuck to the playfield, moveable pieces and special pieces like color changes, direction rotators, teleporters, and more. The game can have up to 25 of custom OGG/MOD music files and has a built in level editor!
