The levels are very well crafted, I had to be precise about my movement to go through the levels. I would have loved it if the game restarted from the same level though and not from the start. The concept was neat too. Was a bit sad to find only 3 levels, but hey considering its a jam game, very impressive still! Great work!
Edit: Forgot to mention, the movement did feel clunky a bit, i think that had to do with having to press the arrow key again sometimes else it wouldn't gain momentum while the character is airborne. But hey - again this is completely acceptable for the jam and it kind of did add into the need of precision overall.
