Cool gimmick! I like the artstyle, but the block shifting buttons could use a bit more immediate visibility. Wasn't sure what to do at the start because I just didn't know it was a thing I was supposed to interact with. It was also possible to cheese a lot of the levels due to conservation of momentum on the teleport, but maybe that was intended, it was fun to do.
Maybe a short tutorial level would also help solidify the inputs and "button" existence.
