With the lack of in-game guidance it's really hard to tell when I've hit the end of something, where I'm supposed to be going, or if the game is even functioning properly. Needing to spend several days repeating the same scene over and over with no indication that progress is being made is annoying enough, but being stuck in a loop where progress literally can't be made because the game is screwing itself somewhere in the code is a bit of a deal breaker. The fix you've added in was talking about an act 2 finale, but the game still says I'm in act 1. I tried the fix, since the earlier conversation was talking about Hana, and I do have her around, but all it did was make the one cutscene play twice, and then nothing new happened. It did also fix a problem with Maki, who gave me the same generic scene like 10 times in a row, before proceeding with actual scenes once I tried the fix. The amount of clicking through all of the screens just to replay the generic scenes over and over is a bit too much of a grind to start over from the beginning, so I'll be giving up on it for now.
For the screen transitions, I think the one extra hallway in the school isn't necessary, just have the classroom and rooftop available from the one main screen. The one extra screen that has half of the same locations just sort of clutters the school up. I also think the world map button should generally always be available, you should be able to disable it for specific scenes when you need to railroad the player. Having to click into the living room before being able to leave every single day gets old.
