The game features the character customization and character class system from the Etrian Odyssey series, and the dungeon crawling from the Mystery Dungeon series; the player's party, which is made up of custom-made characters, ventures into randomly generated multi-floor dungeons, with the objective to reach the end of each dungeon."
