You know, as I was playing this I realized it would perhaps be less linear-y if it was a trainer. Kinda like WT but with this character instead. I think it would be cool.
Also, when I reached the cock worship point, I thought it should *start* with that. It's very weird that cock worship happens so far down the road, after the MC has already done anal, blowjobs, etc even with people outside the gloryhole. Cock worship should happen imho before the first blowjob.
Also also, I think I've said this before, but the character's sexuality jumps way too fast towards enjoying cocks. Just as you're reluctantly doing handjobs in a gloryhole, suddenly, you are fucking a client in your bed and having fun with the act.
At the points where the character can "ask for help", I always thought that the MC is having so much fun (seemingly) that I had forgotten the point was to escape.
All these, however, would be easily solved with a game built as a trainer. Or a VN. I mean this is practically a VN anyway.
