Absolutely amazing! I can't belive you made this in 3 days. The only thing I would say to improve it would be to randomise the error/restart a little more and to make the level change the way you complete it in a little more than you have done. All in all, a really great submission!
If you have any time, I would love it if you were to check out my game as well. We both seemed to have used similar glitch effects :)
