Very well done. The moving mechanic is a lot like the game "VVVVVV", The puzzles are well designed, like concept of looping world and reverse gravity, all levels are well designed. The player movement will benefit from a bit more polish.

You’re totally right — it definitely needs some polish. At the beginning it was going to be a more traditional puzzle platformer, so I polished the game around that idea first. Later, I decided to try a VVVVVV-style concept, which ended up feeling more natural to work with.
Unfortunately, I was running out of time and needed to focus on establishing the player movement before making the final levels. So yeah, the character still needs more work.
