The idea of mixing a medical simulator and a erotic "soap opera" in a game is something new, for sure, and it works, but I think the medical part is too complex for a game like this, and the story part advances too chaotically; too many characters presented at the same time and too many argumental arcs. I'm not sure if this is a game of dates, a visual novel, a game of mysteries and murders... Maybe a less ambitious approach at the beginning of the game would have been better. New story arcs could have been added after finishing the previous ones, like the chapters of a TV serie, and that would allowed a better evolution of the MC and the others. I always prefer quality to quantity. I see a lot of possible paths and possible girlfriends, but not really well developed. I would have prefered maybe a couple of main paths really well explained and presented: the sister and the nurse, for example. And then, from time to time, some short secundary stories of sexual adventures with patients, colleagues, Vanessa and her boyfriend for exploring threesomes with other characters or people who likes contents about gays...
Other problem is the grinding or "Groundhog Day Effect". The game is too repetitive. For example, the dates are always the same thing and doesn't add anything to the game. If there were only a couple of paths, the system of dates could be more polished, and not just "go to the beach twenty times with your girlfriend X and see always the same image"
Also, I think that more kinky in the scenes would be good, without forgetting the romantic part.
Anyway, THIS IS A VERY GOOD GAME. But it could be better, IMO.
