Crazy backgrounds, good music, great idea and controls are pretty good. Biggest issue is the design and difficulty. It's pretty cute that you're given these death messages but the game is hard in an obtuse way, not a fun way. You can't kill enemies with your weapon as far as I can tell and they stand right in your way so you either need great jump timing or the diamond powerup. I can get past the gate jump in the 2nd level but without the diamond power up the bone guy is impossible lol.
It's frustrating because the game seems like it'd be really fun to play if the levels were laid out better.
