Interesting and cool game! One of the coolest uses of the theme I've seen, great idea. The movement was also responsive and snappy, good 2D-platformer controls. The puzzles were a bit simple throughout (although the first one is perfect, simple but effective in showing the player how the puzzles work), but it was still quite enjoyable. I may have beat the TNT level without the gimmick twice, though. I will note I did get a little visual bug where it said my save scum ability was locked but it wasn't after accidentally clicking the Main Menu button in the bossfight. I also never ended up beating the boss, admittedly it's more of a skill issue, but the lack of battles makes it quite the difficulty spike.
Nevertheless, I'd definitely be interested to see more of this, epic idea and fun little game!
