Cool idea for a puzzle game, and it was explored really well too. I feel like you hit the perfect length here, where the mechanics aren't left underutilized, but there also aren't so many levels that it feels like you've exhausted everything you can do with it. Only complaint, as other people have pointed out, is that the platforming is a bit precise. There were a few times when playing where I couldn't quite tell if I was having trouble because I hadn't figured out the correct solution yet, or if I was doing everything right and just couldn't make a jump. Other than that though, I definitely had a lot of fun.
