Go right 1, then back and down, push the boulder right then go up to the top, right and get the torch. Go down and right at the chest, down one, right one, then stand still directly ABOVE the TNT and light it by pressing down.
Now go down, get the key then go right, go up to the top, go all the way right, then go down, get the purple key, go down to the bottom, get the torch, go right, go down 2, go left, pushing the boulder then go up 2
VERY IMPORTANT, go one up, then one down, one right quickly but carefully, otherwise you’ll get blocked.
Go left, get the two diamonds, go up 1, left 2, down 2 to get the key, then all the way left to the chest, get the torch, then light the TNT, go one down from it, then 2 up, 1 left and well done, you’ve completed the level.
