I'm also having the same problem with the Windows Version. All 3 Choices(Gym, Library, Music Room) on Day One tends to bug out making you stay in the dorm, infront of where you're supposed to be teleported into the next scene and the game becomes uninteractable, softlocking you.
This VN is quite nice, I like it. It has good artstyle and interaction between the main protagonist. It doesn't much typos and weird sentences compared to other newly made VN's before.
If I could ask, how much is the next update finished? I'll be sure to make more feedbacks in the future.
