"Attack the Light is a simplified role-playing game in which Steven and the three Crystal Gems—Garnet, Amethyst, and Pearl — travel across five color-themed worlds. (...) Similar to games such as the Paper Mario series, many of the actions performed feature gesture-based controls. Simple well-timed taps of the screen can be used to deal extra damage or reduce damage taken from enemy attacks. Other abilities, which can be unlocked as each character levels up with experience, feature unique mechanics such as aiming a shot or repeatedly swiping the screen."
