This is definitely one of the nicest games in this jam.
The visuals and music both are really good and suit the game alot!
One minor bug I found was that sometimes, upon beating a stage, the next level won't have a collision or smth and I fall through the floor ;(
But considering how you are 12 (how) AND its nice polish AND that you made this with no engine, I consider that a MAJOR well done! :)
