Really great idea and a fun game. I wonder how the level is generated. Did you create preset level areas and then randomly called them?
Three suggestions.
Player should have more than one life. As the game is quite challenging, it's frustrating to start over every time.
There should be some warning or invincibility moment when new obstacles are created. Happened several times that I was just staying and then got killed for no reason. At least a death animation so that you see what killed you.
As the level has many floors there should be some indication of places where you die when you fall down. Either water or black holes or anything, just to be able to differentiate from usual platforms with some floor below them.
A bit more polish and it would be a really fun game. Great job for a jam game though!
