Well it had very interesting gameplay, there Corrupted Morals tag for it but not in a bad way but rather than for the "more lewd" way i think
No body modification tho, girls change there suilt (those look cooler in my opinion) and behavior toward the main character.

I not play this game yet but look like a very interesting game since it had those tag Trance / Suggestion ;Corrupted Morals ;Mind Control.
For the less gameplay but fit the tag you want, maybe try some game from ABALONE KISS

Not sure about corruption part but it had Transforming Girl tags so that could be some corruption there.
