Very Good.
Very nice game! The art is of course fantastic, very Okami-inspired (you're probably tired of hearing that), and that alone is going to catch people's eye.
Gameplay was good-- could have been better. In Platformers, you almost always want to do what Super Mario Brothers introduced: Player-controlled jumps. It feels more natural if you jump higher the longer the button is pushed. Enemies felt a tad repetitive in spots. The combo system was great, even though a lot of them didn't make sense >.>
Sound was a mixed bag. Some of the music was okay, but I found the level music to be grating and annoying after a while. The sound effects were functional but amateurish.
Overall, this is a fantastic example of a user-created game. There's worse stuff than this on consoles :3
