I played this game for for the first time this week and just wanted to say, the art is immaculate.
Vesper as a character is fun to read and her design is great, I admit her basic office attire with vest and tie does something for me. And I must add that I would have been perfectly happy if the game had been entirely a moody visual novel like the prologue.
So far the game is a neat sandbox, though of course as this game is still in development you run into a dozen different construction sites where the game either outright tells you that features are missing or you run headfirst into a wall.
For example my own first run was cut short after 8 days, as Vesper could not progress at the strip club, there was not enough money to buy a blood bag and she went insane from hunger. By contrast the prostitution path and the thief path are more fleshed out and you can actually make it through the game like that. Personally, I would have liked if the journalist and the bartender jobs gave more money, for me it felt always as if all the money Vesper made with these jobs was immediately expended by buying blood bags from the witch.
So, my primary point of contention would be the stat system. For me it felt as if it could use a few more tweaks and explanations. Some stat increases could be bigger if you specifically train them, for example lust increase by masturbation, or the system could be a bit more granular with giving you some bonuses when you hit some milestones. I include the money grind with the two available starting jobs for that too. Another problem would be, that perhaps a explanation for some stats, like charisma or exhibitionism would be useful. What are they good for? Where do you need them? Is exhibitionism really only used for one "quest line"?
And a last thought as a shot in the dark: Is Kat the stripper friend in truth Jules from the high school memories? She immediately recognized Vesper, has a similarly slim build and the side story hints incessantly that something bad would happen to Jules if the father ever found out that they are a couple.
