Thanks for the feedback! I had a feeling the walk animations were rough, since art isn't my strongest skill, so I do want to improve them and get better with more practice.
With the new suggestions for the "wrong exit" mechanic, I'm thinking carefully about what would best fit the game's progression while still fitting the narrative of separating the player from their companions. I think part of the reason it feels time wasteful is the lack of events in-between while searching, which I planned on having more of.
There are some nuances in what makes NTR feel taboo for some people. The game as it is doesn't do a very good job of establishing the relationship between the player and the characters, so the events lean more towards voyeurism than NTR. But if there was a prologue cutscene that did do that, for example, showing the player character and Fiona in a relationship - which I'm not sure yet if I'll add - then now there's an expectation that in the future, this relationship can fall apart or drastically change, and that's one way some people get that taboo feeling.
