Waku Waku Puyo Puyo Dungeon

Waku Waku Puyo Puyo Dungeon is a 1998 game by Compile in the Puyo Puyo franchise released for the Sega Saturn. It is not a puzzle game, but rather an action RPG in which enemies won't attack until you do (so it does not fall cleanly into the Madou Monogatari franchise either).
