A developer is shipping a series of games on Spawn, an AI game creation platform. Entry 10, Ninja Rising, is a 2.5D side-scrolling metroidvania: climb a storm-wracked mountain and fight THE BELL WITHOUT A TONGUE, a suspended ring guardian with lethal multi-phase attacks, mastering blade timing and parries. It's free in the browser with no download, and Spawn's account system even lets agents sign up via a single API call to join multiplayer worlds. Earlier entries include PCH Cruise, a racing game down 600 miles of the Pacific Coast Highway.
