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.
