I think I'm having the same issue as Animamundi. Couldn't leave the library so started looking around and it froze on the room with the pool table.
Other than freezing, I really only noticed 2 issues.
1. The main character and the female interest both have the exact same face shape, which I thought was a little odd.
2. Some of the rooms you enter (the street and theater) have the main character facing towards the door rather than away from it.
Additionally, I couldn't unzip the folder using Windows 11, I had to use 7-ZIp. Might be worth mentioning on your itch page.
