From the start, go all the way left, collecting the diamonds, then go all the way right until your over a balloon. Press down 1, then quickly go 1 up and 1 left/right. Which ever way you went push the balloon to the other corner. Now go back, there’s a boulder above you, go one up, then go all the way down and quickly 1 left. Get the torch and light the TNT (stay well clear) and get the other torch
Go right to the key, go one up, one left, then one right. Get the chest, push the boulder of the sense pad and go left to the balloon (in the picture) when your under the TNT, press up. Now get underneath the boulder, go one up then quickly go one down one left, now push that boulder onto the sense pad.
