As a Super Meat Boy player I have to say that it controls really damn well. My biggest issue is that there are PLENTY of sections where I just walked and platformed around to find absolutely nothing. Also after exploring for a while I could only get the top crystal in the start and the tutorial one.
The visuals are stunning and the music feels really nice with the gameplay. Easily one of the best entries I've seen in the jam. Not very innovative but the theme is applied pretty well.
