Sadly I don't know any title that established the body mod and mental corruption this well, while offering nice art.
Body-Mod games I like are from GFF (Kuribayashi Chris), but they go into extreme/grotesque direction.
That would be these two games:
Contamination
Oozehazard
Quality-wise games of Natyusyo are great too:
Yuka-Scattered Shards of the Yokai
Yukas Mansion
The Wreck of the Spaceship Todoroki
Most other body-mod themed games are quite lacking in quality of art and/or production.
I'm happy to anyone posting good body-mod games to prove me wrong.
