Run 3 Editor Game

If you've ever wanted to create your own impossible space tracks, Run 3 Editor gives you full control over the classic gravity-flipping platformer. You step out of the shoes of the alien runner and into the role of the architect, constructing 3D tunnels block by block. Place regular tiles, crumbly platforms, and massive gaps to design the ultimate obstacle course.

The beauty of this sandbox is how seamlessly it blends building with playing. At any moment, you can switch from the editor grid into play mode to test your own creations. The signature physics are fully intact: touching a side wall rotates the entire stage, turning vertical surfaces into your new floor as you sprint through the void.

Controls

• Mouse: Choose materials from the palette, click to place tiles, and drag to rotate your view in editor mode.
• Arrow Keys / WASD: Steer left and right or jump while testing your level.
• Spacebar: Alternative jump key.

Tips

• Design in 3D: Remember that players can run on walls. A gap that looks impossible on the floor might be easily bypassed by jumping to the ceiling.
• Test incrementally: Don't build a massive track all at once. Playtest short sections as you build them to ensure the jumps are actually possible.
• Mix tile types: Use crumbling tiles to force players to keep moving and prevent them from backtracking.
