I think I might be bugged? I load into what looks like a sample scene and my jump height isn't high enough to get out of this room. I can't figure out how to save my progress either, it looks like there's a J on the art but J key didn't do anything. Restart level and level selection seemed to just black screen. If I'm doing something wrong would love to know and give it another try!
Edit: I did really like the screen shake on landing a jump too!
