Method 1 (by Davitto)
This level is easy if you look closely at the movements of the drones, going right is easier, first, you walk just left to the door, wait until the drone comes up, and jump over it. Quickly go up and past the drone on the right wall, it won't get to you if you do it right, activate the door switch, and wait there for the drone to return, when it starts going down again, that is your chance, go down, but be careful as the drone will keep going straight, so you need to enter the niche for a moment and go down fast, the door is just a few steps away!

This level appears easy, but can be quite challenging. Wait until the drone on the left-hand side has gone into the indentation and jump up in. The drone should go right past you. After it does, walljump into the top indentation and wait for the top drone to move completely to the right. When it is almost ready to come down into the bowl, move left and jump over it. Stand on the small projection in the top right-hand corner until the right drone goes into the bowl. After it does, jump in, go out, and run at the door like a madman.
