Man... amazing game! I just finished. Really hard that last level!
Just a couple of things:
1) The "Enter" when you pick the cat food. Not bad, except the cat keeps sliding until you regain control of it. Problem is in some platforms, that lead to certain dead, when, if you freeze it's movement when the pop up... pops up, you have more chances to survive. I have to pic the food with my finger over the Enter to avoid that.
2) The platform edges are very slippery. I guess you use a capsule collider for the cat, so maybe adjusting the movement speed to give more precision when jumping.
3) The rewind function is cool, except when you use it in a short period of time, leading the cat in a position that always dies.
Example is when you die, you rewind, and stop in what you think would be the correct moment, but missed for a little, and the cat resumes and fall. If you rewind again, the first point of rewind is where you stop in the first rewind. Hope I explain it correctly to make the point.
This are really minor issues that could be easy to correct.
Apart from that, the game is really fun! Great work for a week! Congratulations.
