Tumblestone is the first original action-puzzle game of the past fifteen years. Race your friends in multiplayer or challenge yourself in story mode. Solve progressively more difficult and creative puzzles, help a sausage make friends, and find out what happened to the Tumblecrown.

Features:

• Local multiplayer: Up to four players on a single computer or console.
• Online multiplayer: Play online against your friends or make new ones using Tumblestone's ranked matchmaking system.
• Bots: Have an open slot? Play against the computer. But can anyone withstand the punishing Nightmare bot?
• Story mode: The 40+ hour story campaign will test your puzzle-solving prowess. Featuring 10+ gameplay modifiers, challenge puzzles, and boss battles.
• Arcade modes: Kick back and relax with the casual Marathon mode, scratch an intellectual itch with the Infinipuzzle mode, or get your blood pumping with the fast-paced Heartbeat mode.
• Leaderboards: Online leaderboards let your friends know you're better than them.
• Quests: Hundreds of unique quests to complete.
• Stats: Rank up, then compare how you stack up against your friends.
