I snuck two dice into the ending door lol. After that I figured I could do the same to the mannequin from the lamp and took him to the end too. It seems that he can't trigger the pressure plate for the door like dice, so we can't bring all 3 dice to the end, unless there's more objects that can open the door.

Thank you for playing our game! Yes, sadly, the project has some bugs in certain places, and currently only the dice can activate the pressure plate. However, you can still bring all the dice to the end by taking another route. It is located behind the lamp when the lamp is disabled. This way, you don't need to activate the pressure plate and can proceed to the next room with all your dice!
