Super fun game. Loved the auto aim, it was a life saver. The turtle could do with a few more speed upgrades. Can't wait for the full release ^_^
A word of warning though. For games like this, it's often a good idea to put a level cap on each upgrade so people don't feel compelled to play the game until they're sick of it. Always leave them wanting more ^_~
P.S. The music was fucking phenomenal.
