I wold play again in a heartbeat
Very cool idea. Needs to be developed more by adding more interesting types of ships to infect and more of a story. Where did you come from? Why are they trying to kill?
Also I think you should make crashing your ship into other ships hurt more. At least for bosses I like to shoot lasers at the boss until my health is low then crash into the boss but it doesn't seem like it does much damage.
Cool game once again.
