Really like that jumping quadropus pop noise. The wall jump also feels really nice.
During the later phases, my game started lagging and the physics started behaving strangely. I think you are applying delta incorrectly?
I got to the part with the three elevators. At that point, i started glitching through the raising elevator whenever I would get a lag spike.
This is something thats really hard to get right, so I can't really fault you for getting it slightly off on a jam game.
Otherwise though, great game.
