How to use the winding key on the box
Despite being inside the tutorial of the game, the instructions for using the winding key on the box isn’t as clear.
What you need to do is to hold the box in your inventory. Press space to view the box. Hold and rotate the box to see the keyhole.
You will then need to drag the winding key directly from the inventory menu at the bottom left of your screen. Hold and drag the key to place it at the keyhole.
