Loved the puzzles! You did a very good job easing the player into understanding how the mechanics work. Maybe it's due
to me not being the best with platformers, but it did seem like some of the jumps were very tight with little room for error. There would be times where I would know how to solve a puzzle, but a missed jump would make me reset the level multiple times (mainly levels 9,11, and the final room). Overall a really fun experience, though!
