Runner Builder

Runner Builder mixes speed runs with player-made courses. Race through the campaign, unlock more tools, then try tracks built by other users. The course keeps changing your route with portals, trampolines, checkpoints, boss fights, and hazards that can knock you off the path. Before the run, dress your avatar your way. Pick a male or female character, then swap hairstyles, hats, and other clothes. During races, grab medals, treasure chests, and temporary boosts that raise your speed. Watch for hint markers on the route. They point toward safer lanes when the path splits.

How to play?

Use the movement controls to run forward, line up your approach, and slip past moving traps without touching them. Hit checkpoints as you pass them. If you fall later, you'll respawn near the last save point. Press the spurt at the right moment to smash a monster or break wooden crates blocking the way. Step onto trampolines for long jumps. Cross portals to cover the distance fast. Reach the required level to open the map editor and build your own course.
