What is this game
**Super Mario Defense** is an engaging tower defense game that flips the traditional Mario narrative, placing players in the role of Bowser defending his castle from relentless waves of Mario and Luigi clones. Utilizing a variety of defensive units, players must strategically prevent the advancing characters from breaching the castle's defenses. The game offers 20 challenging levels and 13 unique defensive techniques, providing ample opportunities for strategic planning and replayability. Players can deploy various "turrets," such as springboards and Bob-omb clouds, to thwart the oncoming waves. Upgrading these defenses is crucial to keep pace with increasingly powerful enemies. For fans of tower defense games, **Super Mario Defense** offers a unique twist by incorporating familiar characters and settings from the Mario universe.
