The jam's theme is executed in a very unique approach in your game! It's really hard to come up with some good puzzles that are neither too hard nor to easy - but you've managed it pretty solid! Good progresion curve as well with slowly introducing all the different puzzle mechanics. I would get rid of the respawn button as well and somehow in my browser (firefox) the game window is smaller than the space itch.io provides for it - therefore some crucial game elements at the border of the screen where partially not visible. But that's just a technical issue - very good entry!
