Hello ChrisNihilus, thank you for your feedback! What exactly doesn't open, the box itself or the lock? If there is a problem with opening the lock, then the correct order is important when entering characters.
No, the lock works correctly, but after opening it, it doesn't let me open the lid. The cursor doesn't even appeared to let me know there is some interactable. I managed to make it work a second time and complete the game, but I had to restart the game quite a few more times.
