"You will die a lot either way - its meant to make you mad." I thank you for your honesty!
The layers that you see after a jump seem to be randomized, so there's a lot of jumping in place trying to see the layer you want. The camera also zooms in if you're not moving left or right for a short amount of time, so when you get to see the layer you want you're not unable to see most of the level. And if you happen to hit something while jumping in place it can push you to the side and cause you to die instantly. These things combined are what make it so difficult for me, I was one jump away from finishing the third level (probably, I'll never know for sure!) when hopping in place to try and see how to do it made me slip and fall. ☠
