l1
u1
r1
d1
u1
l1
d1

Go down and around to the LEFT, and apply the same moveset, instead this time, instead of going down, go LEFT to open the door next to the striped panel, then go down and around, then up and follow your way to open up the door next to the exit. retrace your steps back to the furthest left door. open it, go right once, open the switch by going up, go left, down, and right all the way to the exit.
