Method 1 (Easy)
The first part involves a thin shaft containing 3 guided zap drones. Though it is actually possible to jump in between the two zap drones going upwards, it is much easier to first lure the top zap drone downwards, then lure that same drone back upwards, while luring both of the upwards moving drones downwards (see the picture below). As the two drones move downwards, drop down in between them, and then hurriedly walljump upwards, luring the single drone downwards.
Enter the thwump area. Wait for the top thwump to pass, then quickly jump amongst the mines to the exit switch. As you return back to the drone shaft, jump over the bottom thwump. You can optionally go for the gold, though since this is the last level of the episode it is not necessary.
Now, drop back down the shaft. If you didn't go for the gold, wait as the pair of drones reach the top and then start descending, and then wait until the single drone reaches the top too and starts descending. Then enter the shaft. Lure the attention of the two drones, but with a pause in between to allow yourself to fall down in between the two drones. Drop down, lure away the bottom drone (or just fall down quickly so it won't notice you), and then exit the shaft.
