Magnetic Chaos: Keep the Sphere

Physics Survival Arcade by zachstera3, released October 26, 2026. Free in your browser.

Open on itch.io

Magnetic Chaos: Keep the Sphere is a free physics survival game released on itch.io on October 26, 2026. You steer a gravity well that drags a glowing core, the Spark, through hundreds of charged fragments. Same-charge debris is pushed away; one touch from opposite-charge debris or the arena wall ends the run. Runs last from ten seconds to several minutes.

Rules

  • Debris with the same charge as the Spark is pushed away and is harmless.
  • Debris with the opposite charge is pulled in. One touch ends the run, and so does the wall.
  • Brush past opposite-charge debris without touching it to graze. Grazes charge your pulse, a shockwave that blasts the swarm away.

Anomalies that make it worse

SingularityA black hole pulls everything in, you included

The longer you last, the heavier the Spark gets and the faster the swarm spins. Survival ranks run from Static to Flow State to Beyond Chaos, and the live soundtrack climbs from a drone to a frantic pulse. Headphones are recommended.
