Decided to add more rooms in the procedurally generated dungeons to add more variety. Sand rooms can now appear but they are functionally no different than floor tiles.
Added a white sword. It takes twice as much damage. I plan on including "rental shops" where you can buy temporary items like this white sword and they go away if the player dies.
Added an exit tile (actually an object on it's own and not a child of the "Tile" class) that is randomly placed on each floor. Though it does nothing yet.
