Run

Take control of a small alien in Run, a fast-paced platformer set in space. Your goal is to sprint through a series of tubular courses, jumping over gaps to avoid falling into the void. As you progress, the levels become faster and more challenging, requiring quick reflexes and precise timing.

The core mechanic of Run is its unique gravity-shifting system. Whenever you run onto a wall or ceiling, the gravity reorients, allowing you to stick to that surface. Use this to your advantage to find new paths and avoid holes in the floor. You can sprint sideways, jump to the ceiling, and flip back to the floor, chaining moves together to navigate the increasingly complex tunnels.

Be prepared for a challenge! Gaps appear more frequently and become wider as you advance. You'll need to time your jumps perfectly to clear them. If you misstep and fall off the path, you'll instantly respawn at the beginning of the current level. Before you start, you can choose between normal or fast speed to adjust the difficulty to your liking.

Originally a Flash classic by Joseph Cloutier, Run has been rebuilt in HTML5 for modern browsers. If you master the gravity-flipping fun, be sure to check out Run 3D for even more levels, obstacles, and challenges.
