Dungeons are observed to be limited to a global maximum quantity open at any given time. When one closes, another opens. They initially have long timers, possibly up to 300 minutes, until a player enters. Then the timer is greatly reduced. Suggestions v1: cave icons are displayed on the world map for each location that is currently open/ has an active timer v1.1: cave icons on the world map also display remaining time of all active timers Alternative: all cave icons are always displayed and there is some other visual indicator of whether it is open or closed For an open dungeon, the physical location has a completely different appearance as a black/shadowed cave entrance. Upon approaching, player sees a pop up displaying dungeon info and the option to enter. Conversely, a closed cave either appears empty with it being a small alcove/dead end minus the shadow bit or can appear with a new asset consisting of being walled up with stone.
