Decent challenge and difficulty. Game was enjoyable! The few points I would criticize about is how you utilized the rewind. It's okay to rewind because you died but it's rage-inducing to watch myself rewind all the way back to the start and attempt it all again. Maybe rewind just a few seconds before death? It'd be much better to just instantly snap you back to start though; rewinding is more forgiving. Also, my momentum when going up the slopes prevent me from jumping over the spikes, which was a bit annoying. It was a fun experience though and congrats on Game Jam! Rated! Please check out our game as well if you can, and leave a comment and rate too :)
