This was such a clever concept and a really great puzzle game! I managed to reach the end but it definitely took a lot of brain-power :D I really love the art and character animations too. I did encounter a small bug where jump stopped working, even though I had picked up the extra "jump" powerup. I played it on stream so if you want to review you can see it here, it's about 2 hours in: https://www.twitch.tv/videos/1099640781
Oh and also, the "alternative" ending was hilarious :D
