In most regards this game deserves 4 stars. The story isn't all that compelling nor good at keeping interest, but the girl types are right up my alley, art is good, scenes are good and kinky, etc. The interesting thing is that there is a lot of branching character/sex content and, while this is usually a pro, in this game I consider it con and part of the reason for deducting a star.
The writing does a very, very bad job of allowing you to select options that will deliver you to the content you as a player would prefer to see. As an example, I wanted to prioritize mom content so I picked all the dialog prompts that had me spending time with the mom character. Doing so I saw 3 good penetration scenes and I felt content with them. Out of curiosity, I enabled skip/skip after choices and I went back to chose different dialog choices that CLAIM they divert focus from the mom to other characters. To my surprise, by choosing to focus on sister/aunt/etc., I got BETTER mom content than I did by picking the mom options... As an example: instead of spanking the mom during therapy via the mom path, I discovered a scene of MC fucking her raw on the therapist's couch while the therapist pleaded for us to stop but the mom begged for more.
I feel like the dev probably theorized this as a way to increase replayability. This would be true if the player had any control over what they got to see - I was ACTIVELY seeking content with the mother, and got (what I can only assume to be) the shittiest mom content available. If you want to see the best mom content, you need a mod/guide - you cannot get it on your own (naturally, at least).
Considering that dialog choices are the core gameplay mechanic, I consider the core gameplay in this title to be broken to the point that mods are required in order to fix (none of which exist at time of writing, to my knowledge). For this, it gets 2 stars. If the dialog choices guided you correctly, I'd say 4 stars, but they never will be able to due to how much branching in the story there is (unless dev does a huge overhaul which I doubt would be worth while).
