The same here, I looked at that game a couple of years ago (more or less), I couldn't play at the time, I don't know if I had the step by step, or I didn't find it. Anyway, I didn't know what to do and I gave up, occasionally watching videos on pornhub.
and the end of last year, I tried again, and I managed to discover the step by step, I finally managed to progress in the game.
the first two parts were more complicated, but part 3 is much more simplified, which helped a lot.
As for the characters, I don't need to say which one is my favorite, right?
I'm a big fan of incest in games, 99% of those who have this theme, 1% only if I really like the characters.
So I don't need to say, what attracts me in this game, and why I feel sad when I spend a lot of time without content with her.
I know the dev should pay attention to the others too, but I miss her when I don't see her interacting with Joey.
Sorry for this mania of writing too much.
