Content Descriptors:Mild Cartoon Violence
Rating Summary:This is an adventure platformer in which players help Sonic and his friends stop a villain’s evil plans. As players traverse side-scrolling levels, they use elemental powers (e.g., fire, ice) to solve puzzles, collect rings, and battle enemy robots. Players use spin attacks and “cartoony” weapons (e.g., boomerangs, hammers) to defeat enemies; enemies break apart amid colorful explosions.
