i did actually have a concept for a similar concept with a police girl, normal end gets you brainwashed, good end requires faking results in the cults tests to proceed further through the facility
like if theyre brainwashing you to cum when giving a bj, you need to fake it with a vibrator and walk around outside until youre about to cum
only reason i didnt make it was i couldnt think of enough religious tenets to make puzzles out of
