Thank you for your detailed comment! Sorry for the late reply. We've encountered some bugs recently, and some of them you already mentioned. We also wrote a detailed puzzle walkthrough if you're interested.

There are two bugs which may make it difficult to solve the puzzle as intended.
- The assets of the staff notebook (blue) in the staff room are incorrect, and some of the information is not in the right place.
- The departure board in the game can only be interacted with once . Ideally, you should be able to view the information at any time because it is crucial for solving the puzzle.The player needs to go to the correct platform (Platform 7), and they can check this on the departure board. However, due to this bug, they may not be able to do so. We apologize for the inconvenience.
We'll try to fix those bugs, but it seems that we can't upload a new version of the game...
