Fun until just before the yellow key. Then not so fun. If the game had consistently presented that kind of challenge throughout the game, it'd be expected, but not right before your last goal. Frustrating. 4/5 though... great music and overall design. Bosses were hard but not awful.
4/5 for art and completeness of style. Otherwise this wasn't a game and wasn't exactly enjoyable. If it was an animated film I'd have been good w/that.
This game is pretty fun, but it is a good example of element placement. Often the Kongregate tag gets in the way and you click on it, opening a new window, when you meant to click on your 25th big diamond. Developers pay attention to this. Keep your games and links separate.
Poor aim/accuracy. I liked the backgrounds and the artwork, but o/w the lack of responsiveness is distracting. Improve on that and it'd be pretty good.
