At the start, flip the switch and open the door. Make a hairpin turn to the right and follow the path to collect the yellow key. Retrace your steps to the starting room and turn right once you're near it. Press the yellow switch to the right, then face the crates and make a hairpin turn to the right and drop down to grab the blue key. Use the blue switch to the right, strafe right and go through the bars to arrive at the yellow key area. Backtrack to the starting room again, this time go forward and turn left once you're near it to find a blue switch. Flip it to reveal a teleporter to your left, then take it to trigger the exit.
