Most of the humor falls flat, but on the second map, there's a scene in which two parents offer you their 13-year old son for sacrifice. If you opt instead to sent the cruel parents to the pit, there's a short cutscene of the child slyly remarking "It's what they would have wanted." before skipping away. Most players weren't expecting a cutscene for taking a third option, and the unexpectedness makes it hard not to smile.
