It's fun and pretty good, I like the music and the checkpoints are very good and necessary, although it's true that I have some problems with the camera.
It bounces around when you stop and start moving again, it's a bit out of sync with the player's movement and can cause dizziness, at least that's what happened to me.
I understand what you mean. I made the camera moving ahead the player when it’s moving : it creates a bigger play zone on the screen (because everything behind you is lost in gameplay).
