The game is a C-, I remember romanticizing Gil and then getting to the point where Gil's story was unfinished and in development. The characters themselves, which you can interact with are basically okay.
But the plot, though, is a total thrash and wriggle. So it seems that it was written on his knees somewhere in McDonald's. The main character Walter generally written as a stupid idiot who has a billion complexes. On the first playthrough I laughed at this, but on the second playthrough it's starting to piss me off. And Walter is dumb in many situations! If the main character was Gil, Lars, or others, and I had a choice of who to have an affair with, I definitely wouldn't choose Walter.
If you have an 18+ game, why not add more explicit scenes, not just wanking and nudity scenes? You could add social connections for the characters, and the higher the level of connections, the more possible actions - from flirting to cooler stuff. The gameplay becomes wildly annoying because Walter is constantly acting like an idiot.
The biggest problem with the game, I believe, is Walter. He is the worst character you have added as a main character. You need to change him in terms of character, dialogue, and various actions, and improve him further. His dialogues really do seem a bit idiotic.
Because of this behavior of Walter, there is no interest at all in having an affair with anyone, because he is constantly afraid of something. If you give the right to choose the protagonist's name, it means that the player can associate himself with the protagonist, and choose the actions he wants, but this is not in the game. The player, will agonize over not being able to choose more graceful actions than ignoring or disliking some character with whom the same player is having an affair.
Thanks to the developers for putting so much time and effort into this project, but Walter makes for a terrible story. I really hope you notice these problems and redo it.
P.S. If you make a novel like this for adults, make it normal, not for kids 12+. I feel like Walter isn't 22, but 15.
