What I liked:
+ The initial premise of the game - a very unconventional family visits a nudist/swinger resort which leads to their relationships being tested and transformed in various ways (also lots of sex happens). The main character, Mac, has an open relationship with his wife Anne, which creates opportunities for the player to pursue all sorts of characters throughout the game, but the casual nature of a lot of the encounters really distinguishes it from what would otherwise be a regular harem game. Some of the main fetishes/kinks are thus related to swinging, sharing and group sex, though that's not all that the game includes, of course.
+ Choices do matter, and there are consequences for some of the decisions that the player makes. For example, as I've mentioned before, Mac and Anne have an open marriage that is based on mutual trust, transparency and communication, so hiding stuff or ignoring her will obviously have an impact on their relationship. I think, for the most part, the game is pretty clear with what the rules are for the character interactions and what the short- and long-term consequences of the choices will be, and so is quite fair to the players in this respect. There's also an option to just have the outcomes and relationship gains be displayed along with the choices to make it almost completely transparent.
+ Related to this, the amount of paths/routes that the game offers. There's a lot of variation in how the story develops based on the player's choices (will Mac and Anne stay together? will Mac and Leni stay together? if not, who will Mac pursue instead? etc.), and there are options to make it as dramatic or vanilla as possible if one wants to do so.
+ The sex scenes. They really work for me in this game, though I think it's because I just really enjoy the set-up for them and a lot of the fetishes that the game focuses on. The writing and the anticipation is there, the poses are good, so in general the scenes are pretty hot. I will say, though, that there are moments that feel a bit... stiff. And it's not due to lack of 3D animation, that doesn't really bother me, but there are some scenes that aren't very dynamic or a bit on the short side. I think how much you value the visual component of games will definitely impact whether you will enjoy the scenes, but at least personally I would say that sex scenes are still overall good.
+ The inclusion of Bi content. This always adds some spice to the game for me, and what is there right now I'd say is pretty good: the secondary main character, Mac's son Philipp, has the option to pursue trans and male characters and eventually can be steered towards a gay/bi route. This is all completely optional and can be avoided if one does not want to see this content, too.
+ One big fetish that is also a huge selling point for a lot of (or most) players, incest. Kiara and Franzi are major love interests and a lot of the game's content revolves around them and their relationship with Mac and how it changes over time. It's something that starts getting built up from the very first scenes, and the game isn't shy about its inclusion, so whether you enjoy this fetish will have a big impact on your experience with the game. Overall, I mostly* don't mind the way it is implemented, and I like (some) of the choices that were made in how these relationships were developed.
What I'm mixed on:
~ Some of the fetishes that I'm less keen on. Of course there's the big elephant in the room that is the Special Edition. I'll just say I'm thankful that this content is not included in the main game, though unfortunately traces of it remain and a lot of the (not subtle) implications are still there in the script. I guess there isn't really a good solution to this, short of completely removing Tyras from the story, but I appreciate that the dev had gone back to edit the scenes to make it less visible.
*The moments where the Teen Pregnancy kink comes up are also frankly uncomfortable, the writing and the choices around it really take the game in a different direction from the rest of the scenes. To illustrate my point, the usual scenario plays out something like this: Mac and Anne coach Mac's friend Sai and his wife through their first swinging experince, making sure everyone is comfortable and actively consenting the whole time; contrast this with the teen preg stuff: Mac stealthing Franzi, intentionally finishing inside of Lotta even after she explicitly asks him not to, and, looking at the scripts, asking Kiara to stop taking birth control so that he will be able to get her pregnant. Even among the usual jerk/asshole MC choices that the game offers these are a lot more dark and out of place when looking at how respectful and understanding of boundaries the characters are the rest of the time. I can imagine some players being caught off guard by this, so I think it is something worth pointing out.
~ The characterisation being a bit on the thin side. While the relations between the characters and how they feel about each other is thoroughly explored in the story, what we actually know about the characters themselves (hobbies, interests, goals, ideals, etc.), outside of who they want to have sex with, doesn't get as much attention. Obviously, in the context of an adult game set at a swinging resort, these kind of details might seem very superfluous, but I do think it helps in distinguishing the characters and getting players invested in them and their stories, which does enhance the impact the game's scenes (both the sex and non-sex ones) could have.
~ The presentation choice to have most of the interactions outside of sex scenes happen in first person - most of the time the dialogues have the characters staying in one pose, looking straight at the player, occasionally shifting or slightly changing their expression. I can 100% understand why this decision was made, but I think it does make the game visually pretty bland and some of the moments/conversations are less memorable and impactful because of that. How important this is, of course, varies from player to player, and I can understand some not really noticing or caring about this at all. Personally, though, I do think that presentation and the cinematic/visual component are something that can be improved upon in the game to make it more interesting to look at.
I am pretty conflicted between giving the game 4 or 5 stars, but, if focusing just on the sexual content and how well the main fetishes are executed, I think rating it a five seems rather fair. While there are elements of the game that I believe could be polished to elevate it further and overall make it even more enjoyable to play (presentation, character writing), these aspects could be improved in future updates and, as it is right now, the game does succeed in executing what it set out to do.
