Nice work! Looks like there's quite a bit of variety. Though unfortunately I ran into a bug that cut my playthrough short. I was at a checkpoint but it wouldn't let me jump so I was stuck in a loop. But one critique I do have is that restarting after you die is a bit slow. I think it would help with getting that "Just one more" loop if you could try sooner.
But other than that this is solid work! I could see this really do well for having a timer to see how quick people get through the game and the interesting tech people will come up with to make it through. Well done.
