The Good: Great story told in an interesting way; stylish graphics and frequent cutscenes contribute to a gorgeous cartoon style; hint system and hotspot finder alleviate frustrations from previous games; control switches between Brian and Gina in alternating chapters.
The Bad: Gameplay can feel visually static; dialogue tends to be long and not that funny; loose connections between this game and the previous installment make the climax kind of weird; a few frustrating puzzles remain.
