Hi! I haven't finished the game yet, but I did want to report a bug that can potentially prevent the player from progressing. It relates to how the snack table save point resets the area when you interact with it. There's at least one instance during the third(?) loop, where the storage room where you find Vivi can get re-locked after using the key and you can't get another one!
Here are the steps to replicate the bug with File #5 of my save: https://drive.google.com/drive/folders/1wu1vhEM56w2-LQJ7KQsA-ZNaM2roaSUF.
- Interact with the top painting in the eastern hallway to obtain Vera's note
- Interact with the album records on the table in front of the bar entrance in the western area to get the Storage Key
- Go back to the lobby and right-click/use the key on the locked door in the bottom-left
- Immediately interact with the snack table and then exit the save menu
- Viola! The door is locked again, but the key is gone and you can't get another one!
- Alternatively, you can create a save before unlocking the door, but the key will also go missing if you quit to menu and reload the file!
I didn't have a great time when I got softlocked myself and had to backtrack from an earlier save point, but I hope this helps!
