A not-bad platforming/puzzle game, the art style is pretty well detailed, the soundtrack is cheerful, and the sound effects are there.

As for gameplay, it's doable on one player, but I'd really recommend playing it with a friend. The only complaint as far as single player goes, is that the "K" key is pretty far from the rest of the keys used, and that can be pretty awkward if you want to play it alone. Also, the instructions in the Author Comments have a mistake, regarding the Fire buttons, which are actually J/K.

So, not bad overall, needs some getting used-to if you want to play it by yourself.
