a very pleasant game, with characters with well-defined archetypes.
the scenario is perhaps a little too linear (the progression with such or such person is blocked while waiting to progress at a specific point threshold with another).
some missed opportunities also, for example, the fact of integrating futa, could have allowed to add a scene in the history of claire, with threesome and double penetration of claire by MC and Amy. in most games, the players are not very fan of sharing their "conquests", and therefore the scene of double penetrations are rare. the futa allowed to circumvent that ... Amy being very feminine, in spite of its particularity.
Still in Claire's story, her boss’s blackmail story is too underused, especially that in treading on it, she leaves the library, making the place useless. I would have seen the babysitter's blackmail, or even the possibility of "consoling the deceived wife", or even both, using the library as a place of revelation of adultery (for his wife) or as a place of achievement requests from blackmail with the babysitter.
for the boss of claire, considering how he was interested in the library, no doubt, that he will hire a new employee whom he will leave alone to manage the library, as he did in the past with claire. This brings three new girls (the boss's wife (to console), the babysitter (blackmailed and to submit), and Claire's replacement to the library (free sex profile)).
