A neat idea, and well executed. I liked that each level could be solved fairly easily once you knew how, making this feel more like a puzzle game than a platformer. It feels like you took the ideas suggested in the GMTK video on puzzle design and really ran with them - leading the player to a false assumption, but making it clear why the assumption was false.
The trick on the (I think) eighth level felt a little out of place for me - the rest of the levels have only exactly what you need to solve the puzzle without anything to lead you astray.
But overall, it was a very nice experience and it felt like the right length to explore all the mechanics you introduced. Nice one!
