I know I'm very late to the discussion, so my apologies.
The themes described above are also present in Radiant, just an FYI. I'd never create a beta-male MC, let alone a swinger or a cuck. There's a lot of "cheating" in both games, but the player-controlled character only forms bonds and relationships with girls who are loyal and/or "pure." In other words, only the protagonist is a filthy cheater.
And yeah, the other guy is correct that the game doesn't shy away from giving players the option to make decisions that are pretty assholish: as I mentioned above you can cheat on all of the girls and we don't sugarcoat that or put a nice bow on it to make players feel better about their decisions, haha.
That being said, it's all in the interest of good fun and not meant to give any sort of moral lecture or social commentary. The game is your oyster and we don't punish players for their choices, neither in Polarity or Radiant. If this sounds like something you'd enjoy, then Radiant is for you as well.
