"This version of Skylanders: Spyro's Adventure is more of an action platformer than its console counterparts. Players have to complete levels by gathering crystals, which lets them unlock more levels. Each level is littered with crystals, obtained by going towards the end of the level, or by completing a variety of tasks, such as defeating a certain number of enemies, or finding items. Whenever the player finds a crystal, an enemy awakens and a time limit starts. They have to defeat enemies, and get clocks in the level to get more time to ward off the chasing enemy. Unlike other versions, characters can make a jump, and a double jump. This version of the game is set in a different realm in Skylands called the Radiant Isles, and a different force of darkness is faced under the command of Hektore. Unlike the console versions, the starter pack for the 3DS version comes with the Skylanders Ignitor, Stealth Elf, and Dark Spyro."
