pretty good idea just the controls are really bad. ONLY arrow keys are one thing but then you have to jump with space. This makes me uncoordinated and i cant play properly. I highly recommend you fix this before the jam rating starts. You should add w, space and up arrow for jump. a and left arrow for left. And d and right arrow for right. Thats it and i would keep playing this game. I just couldnt play for that long because of the controls and i just got so frustrated.
