P.S this game has a day/night cycle which has an effect on the game - people go to beds at night and work at the morning, ghosts lurk at the graveyard at night etc.
It is not just a day/night off switch - you can see the shadows in the game move from left to right gradually according to the hour of the day.
If that is not enough the world has a sun and 3 moons which cycle around and their state/position relative to you is visible at all times on the upper right area of your screen ( yes, even underground ) , there are many secrets related to the moons orbit ( example - door only opens when all 3 moons are directly above )
I've got the weirdest boner right now.
