Crystal Defenders is a game where you position characters such as Soldiers and Black Mages on the map to defend your crystals against encroaching monsters.

Monsters appear and march across the map toward the exit. Your job is to deploy characters strategically to thwart their advance. Monsters that reach the exit will steal your crystals. The game ends when you've lost all 20 of your crystals.

・Touch controls enable smooth gameplay.
・The iPhone/iPod touch download includes three versions of the game: W1 for learning the basics, W2 for increased strategic depth with the addition of Power Crystals, and W3 for advanced players.
