To do a jump like that (or like at level 95) you must jump BEFORE you reach the wall. You need some perfect timing (or bad luck in this case ^.^) to do it. It happens because you have a little more acceleration when you move and you are not stopped by the wall. I found about this acceleration in a bad way. If you stay where the Lemon 1 is (
level) or above him and you go left, you will die if you are too close to the edge when you fall. If you are a bit further and take few steps before falling, you won't die on the spikes.
