AHHHH this comment actually made my day thank you SO much!!!
to be completely honest most of the routes were me writing them and running on 3 hours of sleep so i was worried that the interactions may seem too rushed or too out of character :') im glad that you think of our game this way though!!
i wish you luck on the oligang route, however i feel there are still some bugs to it so im gonna have to ask you to be careful :^ praying that it goes well though!! Thank you again for your comment, and thank you for enjoying our game!
edit: OH yeah i don't have an average time to get every ending, but i have a feel that it's around 20-50mins+ since I know that the entire game could take up to hours to finish (IF you're doing the teacher route and the OC route) (i have to warn you though the teacher route is more shallow in writing compared to the other routes, since i was in a rush to finish the game and burnout was quickly getting to me, real sorry for that)
