Jump against the wall to the right and, using the left wall, wall bounce up to the top switch, making sure to get the bottom one. Jump into the top horizontal passage and get onto the wall on the left side of the square you stood on. Using this, jump through the middle of the stage, getting the switch to open the door, and hit a wall on the left side of the stage so you don't die from falling. Go hit the left two switches, making your way up to the top. On top, jump to get both switches, then make your way to the right. Using the walls to brace your falling, get to the bottom of the stage and run to the door.
