Loved the puzzles, this game was really clever! only thing i could hope for is knowing what the hekc the button wans from me at the start of the level so I dont gotta do the level a second time when I swap the wrong thing xD I liked that numbers could go negative, although I think negative hp should still be a death. also u can clip through 1x1 laser tile if you swap your speed to be fast enough and get lucky hehehe
