Thanks for playing! I'm not sure if I understand the bug but I think that you might refer to something that isn't a bug. Sometimes the camera zooms in on the fireplace to show you that it's empty. And if the player doesn't have any more wood, he dies. If you do have wood, the camera zooms out and you can go add the wood to the fireplace.
I am planning on remaking the game (not Nokia style) and the dimensions of the different entities will definitely be reworked.
