I've already finished the game and found some bugs in case the developer fixes them.
1- Ariella Monroe and Melissa's gifts don't work, since they don't give points.
2- When Lana Corbin asks me her age, an error popped up and when I clicked ignore the error, it automatically took it as if I answered wrong.
3- When I said that Ariella's favorite color is gray, she says no, but she does give points.
4- Generally, the characters ask you 3 questions, but there were cases with Ariella and Lana that they only asked 2 even if you answered them correctly.
Those are the bugs I found, greetings, I hope they support you and if you release updates for this same game, maybe other harem endings or with another of the girls or even continue with the story.
