Method 1 (Easy)
Jump to the minefield and leap through the mines to the switch. (One way is to jump in between the first two mines on the downhill slope, leap across to the right side, leap again to the switch, then walljump off the side above the mine to the exit).
Enter the second room, get onto the bounceblock, and get the switch in the top right corner. It is optional, though gold is limited in the 2nd and 3rd levels of this episode, both of which are considered fairly difficult. Drop down and enter the main area, patrolled by a laser drone. First, get the door switch at the bottom, but be careful not to slip onto the launchpad, otherwise you face death by launching up into a laser. Get into the gold room and collect all of the gold. It will become necessary later on.
Exit the gold room, cautious of the drone (if you want, wait until the laser drone has faced the other direction before coming out). Run across the mines to the last part, guarded by a lone guided zap drone. Get the two door switches at the top, then quickly drop down into the exit switch room. Lightly jump on the bounceblocks up to the switch (actually, the mines will likely not bother you), then get back to the floor. Quickly get up to the door luring the zap drone away if need be. Again, watch out for the laser drone, you might want to wait for it to go to the other side to be safe.
