Enjoyed it so far(beat it in fact) but I think there should be some sort of visual or audio cue to accompany the dialogue. Maybe even when you get to actually having sex with Jennifer it should swap to you having to rely on audio cues because you can't see down the hallway anymore, but also have to figure out which was a cue for David coming down the hallway and which was just the sound of sex.
Maybe could even make different sort of difficulties for these kind of features to work better?
Otherwise really fun prototype! Not usually my type of kink, but I enjoyed the dialogue/art. Hoping it gets even more risk/reward crazy in the future!
