Wow I managed, but dear God was it hard (51 minutes! xD). I like it, the concept is cool, the music is chilling, the overall experience is awesome. The game is very polished, although I hated the fact that holding the jump button makes you constantly jump.
It would really help to relax the game. Make more "safe zones" where You can wait a little and figure out what to do next, make thicker platforms to make it easier to turn back with jumping (the last level!) or not force the player to jump at the exact moment. I would also add another button to heat up the robot, because mashing keyboard to quickly heat up isn't ideal I think... Especially when You have to constantly think what to do next. Or maybe forget everything above and there should be only one hard challenge per level?
