- excellent enemy variety, with several classic enemies returning, in addition to a plethora of imaginative new foes

Negatives
- the majority of boss fights are uninteresting mechanics-wise and devoid of any challenge
- search party levels incorporate questionable design decisions, including pick-a-pipe and hidden block scavenger hunts
