Hey, really liked the asthetics! Did you make the art?
Some tips to improve:
- makes the rewind a bit faster (if I take too long or go through a lot of tries the rewind is really long to take me back to action)
- reduce the hazard's trigger size (if I barely touch the spikes I already die)
- avoid invisible walls
- makes the slime a little more charismatic (maybe adding eyes and month?) he's lifeless imo
Besides that I really liked and had a good time playing it, good job!
