Hello Sue!
Thank you for playing our game.
This game is for a game jam, so we didn't have so much time to pulsing it. That's the reason why we put "in development" for status and why you find some bugs.
We are not sure about what you mean by "The safe offers text but no puzzle or anything for opening it", if you reached the safe, that means that you have found all the numbers hidden in the room.
The order of these numbers is given by the notebook as well as the clues of how to find them. These numbers are the pin code for opening the safety.
Sorry if you experience wasn't satisfactory. Now that the game jam is over we're focused on fixing bugs.
We hope see you again and enjoy the whole experience without bugs 🤗
