This achievement is really easy to do, even if you don't know any of the shortcuts. This level is actually the shortest level in the game, mostly because you can just jump straight up to the exit at the beginning, as you can see in my video clip. Watch the clip to figure out the fastest way to beat the level if you're still struggling.
EDIT 10/13/16: Apparently cheat codes don't disable achievements, so you could technically just no clip all the way to the exit. Press
to access the cheat menu. Cheats or not, you should have no problem getting this achievement.
