From the landing, drop down into the area below, grab all the gold you want apart from the ones on the lowest plastic block and be careful about the turrent. Go through the gap on the right and land on the slope beside the mines. Jump into the area below, avoiding the bug and through the gap into the area with the thwumps. Jump on the switch, avoiding the thwumps and the bug in the area above, jump into the top exit, grap the end switch, and wallhug yourself into the exit. Yay!
