I like the music a lot. Very intense and sets the scene. Also, I'm sure the code to generate those moving lava platforms was really satisfying to write and see working!
I agree with some of the other people here, that it gets a bit repetitive, But I mean, this game jam is short, so I understand. And if you have more time to work on it, you should come up with a few more mechanics for levels!
This lags pretty hard on my machine. The mouse position and the player token position were desynced if i moved the mouse too fast. Unless that was intentional.
