Art is good, the game could be good too, but it is very focused on perfect routes. Most characters have multiple bad endings. You can't go on anyone right away, but need to get good endings for the brother/servant or the other student in school first and then unlock new options for three more characters.
With translator I managed 5/8 characters routes so far, but I failed at the good end teachers route. I don't understand how you don't end up with a bad ending on day 5.
