I like the assets a lot. I'm not sure if I beat the game or not. I got a key, then later in the level the game over screen randomly popped up. The enemies levitate, and I'm not sure if this is intended or not. But it gets in the way of progressing and makes it impossible to get past them. In any case, this can be interpreted as being ridiculously overpowered, since the enemies effectively become walls, rendering your jump useless.
Also, you can jump on the shoulders of enemies and float out of the map. I had a hard time connecting this with anything in the game, but it was very entertaining.
