The game was fun and challenging.. If you made it even more punishing you'd probably have a rage game XD. I actually was very confused when the same level I died at was the same level I started at. It didn't really make the "Game Over" feel game over. The only thing that changed was the score. And I also was incredibly confused when the level switched. Sometimes I confused the level switching to a game over. Also probably should make how many times you have to do the "there and back" more clear, or do I just do it until the level switches or I die? Anyway good game! Good luck in the jam.
And side note: How did you make a video in four days after the jam. XD After the jam I felt so burnt out to make a vid. Probably cause I attempted a complex idea..
