A hot little piece of shit game.
First, the obvious: If you're allergic to any game featuring a slut (NTS/NTR) wife, this is not a game for you. Also, if you are opposed to humor and porn logic, this is not for you.
What's great about this game? Mostly the wife, but also the other characters. Wife is hot as fuck and super ditzy in a way that's an odd combination of kind/funny/innocent/naive/generous and slutty as fuck. Basically, that makes her sexually indulgent without being soulless, jaded, and evil. She's lovably and adorably slutty, not in a way that most men would want in real life, but in a way that works in a porn game.
MC's friends are jackasses with little to no respect for him who just want to use his wife sexually and shamelessly, and that works in this humorous context.
So what makes this game a piece of shit? Primarily one of the worst UIs you'll ever find--specifically where the dialogue and narration are concerned. Every character gets their own color--not just for their name but for everything they say. It gives the game a vibe like it was created by an 8-year-old with no taste.
Also, the artwork in general is mediocre. Imagine a band full of shitty musicians with great enthusiasm, passion, expressiveness, charm, and charisma: The act works, but not because anybody knows how to play an instrument.
