Anyway, this is my top-down, free-movement shoot-em-up. It features multipart ships and an open upgrade system using 5 distinct powerups. Both you and your enemies evolve, with the most effective enemy going on to spawn the next wave. You have to keep up by upgrading your ship each wave. The system has a lot of different build possibilities, and as I add more part content they'll only get bigger.
