I completely disagree. I check the adult section of itch every other day and it's full of games with the Patreon trickle-content model. Purposely prolonging their games to suck as much Patreon money from people as possible. The story in most of those games sucks ass too and only exists as an excuse to make characters fuck.
Finding this game was amazing. The story is extremely well-written and fully completed so I don't have to wait years to understand the story, the NSFW scene makes sense and is well-designed, and the music has a peak level of music.
The length of the game is also very good however I should mention I played the deluxe version, so I don't know how long the full version you played.
i dont know if this song was used in the game but they are similar enough to me
