Method 1 (Easy)
This is a fairly simple level. Collect as much gold as you can on the top bounceblocks while staying away from the gauss turret. Drop down, use the wall to stop your fall, and land right of the launchpad, right next to the floorchaser. Jump over the floorchaser as it goes left, hit the door switch. Then either lure the floorchaser back left or just land above it. Drop into the next part, jump over the thwumps (activating them) to get the exit switch, while also dodging the floorchaser. In the last part, hit the door switch, lure the floorchaser away, hit the launchpad, and try to walljump off the set of horizontal set of bounceblocks right above the bottom set.
Even if you miss, clambering up this last part is fairly simple. The gauss turret likely will not be able to catch up.
