Hey, thanks for playing!
@OptionSelect I spent a lot of time playing Space Invaders, Pheonix and Section Z when I was working at a construction camp, those are definitely all influences here. Pheonix especially, though this is much less screechy.
Shooting backwards actually makes a lot of sense, I should implement that soon.
The Boss might need some tuning. I've already spread out the parts that shoot at you, and decreased its health. I've beaten it, but I probably have a longer attention span for this game than anyone else. My goal here was to have a game you could beat in a few minutes, so an easier boss is probably best.
@stuartlangridge The shield protects you against anything yellow. White things can't be hurt by your bullets.
