Not that great.
Its got a nice look to it, but the animation was lackluster, especially at the boss battle, which is pretty disappointing. The entire game was absurdly linear, since for the most part, all you do is travel to the right. The puzzles in this game are fairly easy and boring...
The medals here encourage me to replay this game, but unfortunately, nothing in the game makes me want to do that. An honest effort, but it's not enough.
