I am stuck at level [Problems no more] when you are required to do multiple vertical wall jumps, and I can't get them right no matter how I try... At most I could land two on the right timing, but they always seems random and out of control, and very far away from the height I need to reach. On a general feedback, jumping control is the most lackluster issue on the game in my opinion. Sometimes the double jump send me a puff above, others I spring wildly up for no reason....
