I enjoyed it, well done! I felt like the jumping was a little strange... like sometimes either my input was missed or I wasn't counted as grounded when I thought I should have been. But I kept playing until I won, which is high praise. Good job!
Did you finish it? I'd have liked a screenshot with number of deaths and total time saved. If you beat it again, do share. And yes, the jump is a bit strange, but you get used to it. I tried fixing it, but wasn't able to.
