Good, but you can do better.
I know the six seems a bit harsh, but I'm positive you can do better than this. You showed a good eye for quirks by repairing the colors as hearts are collected, and some of the levels- like the vanishing hearts- were very clever... but in the end, it's a typical platformer with a pleasant quirk.
You lost a bit more because the music glitched and stopped playing for me. That seems a pretty simple thing to catch in editing.
In any case, the final battle would have been neat to play- maybe have each color stored in a heart and require the player to catch them in order while the EVIL TOP HAT MAN tries to stop him or... I dunno. Use that imagination! :D
