The first thing you have to do is get a hammer. Then get enough wood to make as many platforms as you need. After you have made all the platforms and the hammer of choice you have to make all the platforms in a line that goes up. Make sure you start a few blocks off the ground but, not too high. (stack them up above eachother). After you have stacked them up where you want them hammer them into stairs facing eachother. When they are all hammered the elevator is ready but, you have to line yourself up correctly. When you're jumping onto them your sprite must line up with the very edge of the block. When you do this you will rocket up the stairs and be where you want to be in seconds!
