As written catherine indeed slips into it through her past behavior and personality and her change makes sense. Albeit it happens in too big chunks in my opinion, it is a pretty fun game. (Instead of gradual step by step evolution Catherine faces critical changing events, but 2/3 of the major ones are while being hypnotized which is not as interesting). The art is great and catherine tempts you as much as the patrons, altough several hours into playing I have yet to find a proper sex scene. All in all 8/10, waiting for more.
