A fun arcade game with a short loop. I managed to get to 3 min 19s with 95 killed. The music suited and I liked the gfx it worked well.
Lots of areas to expand this game later on: more weapons, zoom out, power-ups, different enemies, allies, etc.
I found I'd hit enemies quite often when moving as I couldn't see them in time, so might be good to zoom out a little when the player is moving.
