While I really like the base setup of this game, as it is much closer to what a swinger lifestyle is really like than most of the games in this space, the Engrish and confusing path switches hold it back from being truly great. Really needs to be proofread and it needs a built-in walkthrough or a road map, so we know what the choices change, down the line.
I was in the lifestyle for about 15 years. Me and my partners, would swap couples or do FFM threesomes, I even acted as a bull a couple of times for a cuckold couple. We never played alone(when the partner was not there) and I never played the cuck, although I did watch them, while recovering from an orgasm and vice versa, they would watch me but we never excluded each other. We liked to be watched together as well.
This game has a lot of that, which I like. The English is just bad at times and you have weird choices that somehow block you from future content but you have no idea at the time. Like allowing the couple to be kinky in their car, stops you from a future hookup. All while you are doing stuff with your wife, in public places. While making random choices like that, affecting other things(butterfly effect) is true to life, it is not really what you want in a game where you are the one in control.
