Infinidungeon

Legend has told of the infinidungeon, an ever-shifting maze of chambers full of monsters, traps, and treasure. You know the stories of the four crystals which, when collected, will flip the dungeon, granting access to the deeper chambers. If you are bold enough and lucky enough, you’ll make it to the lair of the dragon and slay it, overcoming the infinidungeon! —description from the designer
