This was a really well done puzzle game! The puzzles were thoughtful and intuitive, and their progression did a really good job of easing you into the mechanics. I love this kind of game, where developers really explore the depths of their "gimmick" (which I think has an unfairly negative connotation). There's some more technical issues, with some strange hitching (in the web version) in level 10. Additionally, it's a little frustrating to be booted out to the main menu whenever you die, but these are very small issues. Well done!
