Carot shows what happens if you place Geometry Wars in a scrolling maze. The pacing of the game reminds me of the C64 classic Paradroid, which is a good thing. I like building a slow wall of bullets around me and then attacking. Unfortunately, there's not enough game here to recommend. Given the hardcore technologies employed (C, SDL, OpenGL), that's understandable. Currently, the level you start at is the only level there is. It's fun, but really needs to get harder.
