Hi, thank you for playing and the video
I am glad you liked the game mechanics.
You were very close on finishing. The game will notify you if you do it though.
The chess puzzle is all about setting up the chessboard. Nothing more. I will make it clearer for the player in the next update.
The hammer isn’t important. I think I will remove it for the moment, because it confuses players when they find it.
The paper with the colors, was a clue for the book shelf. It shows how the books should be placed.
