At first I thought that the dimesion-shifting would be similar to Fez's camera rotation, but I have quickly caught up on the fact that the mechanic is different. However, even thought I have tried multiple times, I could not truly understand it. I know that my position matters when dimension-shifting and that all four buttons seem to do the same thing, so I'm stuck.

The minimalistic design was nice and the game very responsive.

Interestingly, I have managed to trap myself, where the respawn mechanic (very good one, I must say), kept spawning me at an edge of a block, which caused me to fall indefinitely, bypassing the bottom killbox.
