Defend Medusa's undersea base in a compact endless tower defense arena. Tap empty shell pads to place Basic, Frost, and Power turrets, switch attack modes, then use each turret's own Upgrade button to open five upgrade paths for damage, range, speed, shot velocity, and special effects. A restart icon, sound toggle, and pause button keep the top controls clear, and tapping anywhere resumes from pause.
