Wow, this game made me go completely cross-eyed after about 10 sec of game-play. If the background didn't look so much like the cannonballs I think it would be more user friendly, but I still enjoyed it.

Not bad for a 1 day build, but I noticed an exploitable bug in that you can fly off the bottom of the screen to shoot the enemy ship free of danger. Also, very, very hard if you chose not to cheat.
