Really cool puzzle game! I think I Finished it. Room 131 just sent me back to room 5.
I actually had a lot of fun with this! The last level was probably my favorite because I felt like I was able to solve each element one at a time and was the easiest to wrap my head around without feeling like I was just randomly guessing.
Feedback:
Levels 7 and 13 were a weird difficulty spike for me and were much harder than the levels before and after.
Backing up without pressing R could sometimes be a bit finicky. Might have been nice to be able to press R to start unwinding and then interrupt it where you want to be.
You can sometimes see out of the level when grabbing the key at the end of a level
