Good game but anyone how to reset the game for mac

The game is pretty good, graphics weren't that good and the art style is okay. The animation is pretty smooth and the sounds are okay. I was wondering if anyone knows how to reset the game for the mac, my skill distribution has utterly screwed me over in this one on hard mode. I HAVE beaten the game on hard at level 44 on the one in godlimation's website, and it took forever. I was disappointed that after beating hard mode, you only get to start at the beginning of hard mode again, would of been nice to get his equips or something. Overall I spent 4 hours on it, and it was pretty fun.
