I think this would definitely up the intensity for the game but I think it'd be neat if when we hide in wardrobes there'd be some kind of breathing meter if we stay in the wardrobe for too long it will deplete and maybe our character might pass out but we can still be able to get ourselves back up though.
But also I think it would make it fair too since there's probably some players who hide in the wardrobe until the game is over. (I am unfortunately one of them especially when I'm the only one standing)
