Jump Movement

A hardcore 2D platformer with a minimalistic design and pleasing graphics.
You can only move left and right while jumping until you hit the ground. In each location you have 6 rooms with many obstacles on your way to the finish line.
In total there are 5 locations and 5 levels of difficulty - 25 combinations in total - try to pass each of them in the minimum time.
Can you do it? Doesn't sound too hard? Then good luck, and try not to smash your phone :)
