How should I interpret the blackboard game room?

The blackboard in the game is arranged in a certain order, based on the numbers 0-0, 0-1, 0-2, etc. in the upper left corner

I see there are still many areas that haven't been perfected, such as the audio and the actors, etc.!

Well, thank you for your valuable suggestions. We will make revisions based on your suggestions.
