Thanks for making a great game!
I've enjoyed Saiko no sutoka alpha 2.0.1 and it's fantastic!
But, i should report a bug that is accidently found when i was trying to beat hard mode without any damages.
I closed the door of the library at 08:50 ~ 08:55 to earn some time to escape from Saiko-chan.
When i visited the main hall of 2nd floor again at 14:50, i've noticed that she was stuck in the door.
Hope this helps :-D.
