I thought this was a really fun little fast paced shooter (I hit a 54 kill streak before one of the black armoured goons got me). The only thing that surprised me was the fact that the powerups on the floor stopped the projectiles so should probably not be in a collision mask that the projectiles are looking at, and occassionally an enemy would shoot me with projectiles being fired out of their back! Maybe that will teach me for trying to be all sneaky :-)
Great little jam game - nice work. The pacing of the game was excellent.
