Surf a living probability field |ψ|² and lay solid matter ahead of a walker that never stops.
The walker is always walking, and it waits patiently at the edge of a gap (with a soft pulse) until you give it ground ahead — get it across the chasm to the green exit. The field breathes on its own: the bright lobes drift and pulse, so a collapse is about timing a moving target. You can only collapse where it's probable enough — the crosshair is green when allowed, red when not. Tune the emitters to brighten the spot you're aiming at. Collapsed platforms decohere back into the field after a while (they shimmer, then fade), so keep laying matter ahead of the walker. Hit P any time to freeze everything and plan — you can still aim and collapse while paused.
