Are you talking about the elevator part in level two? If so, you are supposed to wall jump on the wall (which if you didn't know we had a wall jump it's the thing you collect on the first level, I will make an update soon with text since we never tell players there is a walljump). Also, W is to aim upwards. We are going to release some updates soon for the game like a balance one and a juice one so hopefully that addresses some of the issues you see in out game.
