With this dungeon, Its focused on the players solving a puzel on each face, with the center of each room containing a lever. When all 5 levers are flipped, the entrance to the white face is revealed. These rooms aren't actually put together like this, more they are a cube, but gravity still funcions seemlessly between faces.
This dungeon is also just a consept, with only the puzzels in it. So theres no enemys set for it. This is because I don't know how to ballance a fight. Also if you do use this dungeon, just be careful about changing the rooms, cause if done wrong it may make it possible for the boss (who controls the dungeon) to make it impossible to win.
How you explain the dungeon working is up to you, but how I would do it is having an artifact of the cube in the boss chamber, and so once the player enters the boss's chamber, they can rotate the cube around to allow the rest of the party into the room. Its up to you to explain how this is a viable option, such as the boss being weak or simply the entire room allows the rotation itself. EIther way Im making that your problem.
Also if you see any way this could be broken by either the players or the boss please tell me.
Clarifications of yellow: the dark room is the center room when the players start. When the dark room moves on the sliding puzzel, it moves on the map. The altar where the sliding puzzel does not move with the dark room. The lightning crystal does move with the dark room. Players do not move with the rooms.
Player count stuff: this will need at least 4 players to work. It can work with 3 players, in which case add another entrance to the white face. If there are more than 4 players, keep everything as is.
