I do not understand the vitamin system, or if it just Claire only. I don't know, because I have no interest playing as Claire, I have 0 interest in F/F content or engaging in M/F content, so the entire game kind of feels very bare bones for me. Cuckolding content is not interesting, or it would be if everyone participating was male. So there is about a couple of scenes or interesting things for me in the game.
I just generally don't want Clare around, and the divorce thing is locked behind a lot of grind. I wish there was a way to decide if you want to start the game married or not. Though there may be an oversight or bug where Clare still appears even though you have divorced.
Clicking through the apartment building is kind of excessive, the previous system where you travelled through the apartment was more intuitive. There is quite a bit in prostitution that you need to re-click, accepting to do actions with few people. The time advancement thing does not work at all, but that may be just a bug.
These are my opinions, but I do want to see more of the game. But for now, there is very little for me in the game. Though, this game may not be made for me (man who is interested in only m/m content) in mind, which is fine.
