Really good execution. The art was great, and the soundtrack was good, I just wish it looped properly. My only real gripe is the amount of trust falls in the game. They never punish you, but it's a personal pet peeve of mine when you have to jump down to somewhere you can't see. Other than that, I think it's a little too forgiving with the health pickups. I'd maybe have one spawn every other hit or have them heal a little less, but that's more a balancing thing. This has a lot of potential for a full release, though :D
