This is a side-scrolling puzzle platformer starring three characters, each of which has a special ability. The warrior is best at combat and can use his giant shield to block attacks. The thief has a ranged attack and can swing across gaps. The wizard can levitate objects and summon useful items into play. Each character can be leveled up by collecting green gems. While playing a solo game you can switch between these three characters on the fly. But Trine also supports local drop-in/drop-out cooperative play.
