The hand is very ugly

I took another look at the teaser video and it seems to be like Skratus said, that the lantern follows your view as you look up and down too. It would just look silly if you're looking at the ceiling and the lantern is stiff like it doesn't follow gravity.

The easiest way around this would probably be to lock the lantern at the position it is when you're looking straight ahead, so that if you look up/down or lean it will stay where it is and just move out of view.

Of course, this is a minor problem but it would surely help with immersion if it doesn't look completely unrealistic
