Hey, good job putting this together in one person :) Unlike us, you went for a reasonably scoped game for the jam.
Note that physics are dependent on frame rate in weird way where my jumps are too small on 120 Hz, I had to set 60 Hz in order to progress with the game. I’d expect they be bigger cause you didn’t take delta into calculations, weird… I think the game is only playable on 60 Hz systems.
