The concept here is super cool. I really enjoyed a lot of the levels. Some of the levels were a bit frustrating because I would go through and screw up a jump or something on the last loop and have to redo all of them. A suggestion that I think wouldn’t break the mechanic would be the ability to retry the loop you are on (I realize you can’t let the player redo a previous loop while still preserving the puzzles, but maybe the current one would be okay).
I will also say that level 2 was a surprising jump in difficulty. I thought you had to get on the platform so I was trying to time jumps so that I could jump off of my previous loop in midair, but then later discovered I could just stand on my previous loop and touch the bottom of the goal.
Loved the art style and really creative puzzles. It’s amazing that you made so many of them in such limited time.
