This level includes 4 laser drones and a huge stash of gold on the left side. Use your judgement's calling to decide if you want to go for the gold. It actually isn't that hard to get despite the drones. All four drones will fire at you at the very beginning. Jump onto the half circle with the gold and jump up to collect some of it, then take shelter on the wall. Get more gold if you wish, then run right and grab the exit switch. Finally, get back to the door.
