I don't know if you've ever played Superhot, but after you beat a level, it shows what it would have looked like in real time, and you feel like the smartest person alive. This game is the opposite of that. You get to the end and just have to watch as past you struggles and struggles and dies on spikes they couldn't see, and you're powerless to stop. There is absolutely nothing I would change about the rewind, however, it might be nice to see the spikes before you start the level. Amazing job.
