Stuck on this level TToTT
On the off chance that it still matters a week later and you haven't found a way past it already after posting this, the way you do that level is you hop up onto the block right above you and then jump down and to the left into the green line, then let yourself rebound back up to reach the door.
The trick is that the gravity shifts preserve your speed, so you can reach the same height you started from when you make a jump.
Hope that helps!
