Cool idea! Managed to complete all the levels. Just a couple nitpicks:
It was a little difficult to figure out what the function of each button was. Sometimes a button would make platforms appear, but it was difficult to know where (especially if it didn't show up on the block cam). Sometimes the button would actually move the block which was really surprising. As a result, I didn't really feel like I was solving puzzles, I was just kind of stumbling into the solutions.
Also, sometimes I would fall into a zone that would reset the level. I wasn't really sure why it happened sometimes and not others.
All that said, I think this was a great concept and I really enjoyed the art as well. It was fun controlling the block with the time-reversal power. Nice work!
