Hey, played and left a rating and wanted to leave some extra thoughts. Loved the little animations on running/falling/idle, camera doing a little spin on entering the level, and the tutorial got the mechanics across really clearly.
I made it all the way to the end, but I think some of the solutions are really difficult. It requires you to kind of make a checklist of all the things that could be reversed and have to test them all. I didn't realize the entry portal could be reversed as well so I spent a bunch of time running around the level trying to figure out what I could even interact with.
My last recommendation would be for some onscreen indicator (beyond color) that tells you if you are reversed or not. Color is good, but I forgot very quickly which color was supposed to be the reversed color.
