I understand that this game is very popular, and I am sure it took a lot of time and effort to create it, but there are still some things that made me give it 3 stars.
First of all, check out the tags. This game has some sketchy, and IMO disturbing stuff that I am really not into (this is all subjective, I understand that many people like it). Humiliation kink and rough sex is fine, but Myriam can end up being continually abused and raped, which is too much for me. This can also be a trigger for some people, so I suggest you pay attention to your choices.
On the other hand, in terms of content, you can shape her story, she can become your project (as the name suggests), and you can turn her into a dominant woman who knows when to say NO, and dumps her cheating husband. Or... she can be a completely naive and submissive person with essentially no power over what is happening to her in a sexual way. Also, there is bestiality involved, as well as alien sex. Some things are skippable, but you are unable to see which path you're going to be following - there is no warning about certain kinks, so this part of the game could be improved.
The visuals are fine, but I don't find Myriam as attractive. Her build is very big and bulky, and besides having big tits, her looks aren't special in any way. I would even say that her face looks rather weird in some scenes. This, however, wasn't as much of an issue for me as the lack of animations was. Or the non-existence, to be more precise. I think that this game would look more attractive to players if animations were added, because there really is a lot of sexual content.
As for the playability, this game is very long and gives you many different routes, kinks, fetishes, and many hours of gameplay. It is fun to see where your choices take you though, kudos to the dev for creating that many options, in the end you are the one who is clicking on the options, so I definitely cannot say that the story is linear, or forces you into doing something you don't want to. Still, some things in this game aren't appealing to me, so I am giving it 3/5 stars.
