Loved the polish of the game, and it's a really neat dungeon-golf idea. The level exit is especially satisfying. I had a lot of fun playing this!
Having different characters is a neat idea, but I don't feel it was clearly explained what their different "abilities" are. Eventually, I assumed it was the "horizontal/vertical" power, so that's cool. Also, sometimes the bounce seemed to go in the wrong direction (opposite of the momentum).
