Neat game idea, I had a good time trying to fine-tune my settings to make the jumps as easy as possible. That square can CRUISE on max speed, haha! Thoughtful of you to add lots of checkpoints. I might even recommend adding MORE checkpoints. I've noticed that many game jam games are way too hard and that just results in nobody playing them to completion. Yours is already way better at checkpoints and difficulty than most 48-hour games, but going even further is just my two cents. It's also impressive that this game is only 5 mb, my hard drive is very happy about that. Good job!
