Unhearted: Drakes Misfortune 2

This superb level is absolutely rammed with detail, and uses the space incredibly well - having you come back on yourself and walk behind areas you have already been through, or reuse certain areas multiple times. It also contains a really fun catapult contraption. Although it uses the 50 layer glitch, which can make it slightly confusing at times, this is a top notch puzzle based adventure, with an amusingly sarcastic story line to boot, and I highly recommend it.
