no use having markers when youll need to learn the map anyways, theres no way someone will sightread the entire map especially when its parts arent just holding keys.
still, this map is awfully executed and was made just to mess around with track ideas. i doubt anyone will try passing such a niche track hence the halved assed decoration.
different just for the sake of being different. its bad but accomplishes its purpose for being unusual, and thats it.
