I liked very much the day night cycle mechanism, that fits well into the theme ! At one point I've been wondering if the map is infinite so I've been walking all day long and all night long in the same direction, it seemed to be indeed infinite... I regretted that experience when I found out I had to walk back to the portal haha
It was fun, maybe the day mechanism could have more variety than just looting some graves but that doesn't matter too much because days are short enough
