Method 1 (Easy)
Collect the gold in the area you are in, then enter the mined shaft patrolled by a lone guided zap drone. It shouldn't bother you too much, though to be cautious, you can lure it away into the beginning area.
Collect the gold in the middle if you wish, then jump across to the door switch. Grab it, then carefully make your way to the right side again. Collect the remaining gold if desired.
Exit through the unlocked door and drop to the bottom, and slip into a room guarded by four zap drones. Systematically collect the 5 door switches and the exit switch. One possible route is shown below. The bounceblocks make it fairly simple to collect the switches; to reach the higher ones, perform frequent double jumps, and use walljumping on the blocks to your advantage also. Take your time getting the switches, since this is the last level of the episode, and wait as long as you need (assuming you have enough time) to let the drones clear out.
After you're done, head over to the left side and climb into the exit ledge, and reach the door.
