This level isn't too hard, especially if you know what to do. From the start, drop down, and get into the first cloud with the zap drone. Avoid the guided zap drone (you can lure it out of the door), then flip the switch. Emerge from the cloud, and work your way up. Get to the area with the gauss turret, and get the gold. It isn't too tricky if you keep moving. Get to the second cloud, and draw the zap drone down from its patrol zone, then activate the terminal. Wallclimb back up to the gauss area, then cross it and get back to the starting wall. Jump and walljump to the exit cloud's wall, then wallclimb and surface. Exit the level.
