COLLAPSE — a wavefunction puzzle

Surf a living probability field |ψ|² and lay solid matter ahead of a walker that never stops.

How to play

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.

aim the crosshair
1 2 3
select which emitter to tune (active = gold)
Z / X
tune the selected emitter's phase (brighten / dim)
Space
collapse a platform at the crosshair (only when green)
P
pause — freeze the field & walker; aim / collapse to plan
Enter
send the walker back to the start (run again)
R
clear platforms and reset
