This is one of the best games I’ve played from the jam so far! Very unique and interesting controls, and the puzzles you designed around them were fantastic. The only change I would suggest is maybe move level 9 several levels earlier. The difficulty seems more on par with levels 3 or 4, but maybe I was just much more used to the controls by then.
Oh, and it gave me a chuckle when I noticed what you did in the final level. :)
