the dumbflies have left the webcam and entered the brain.
every fly carries its whole old mind: three 32×32 thinking fields — perception → memory → decision — that drift, kick, decay and settle into patterns.
each fly has a real eye. it is rendered by the same raymarcher you see through, so the moons lens what the flies see, the mirrors multiply them, and they can see you — your face is the orb you carry. they eat light and motion, they mate when their decision field fills, their children inherit blended fields.

the descent still runs: find the gold crystal, open the seal, go deeper.
F picks the fly you look at · R rides it · H hides the panels.
first launch: the GPU driver compiles the shader once, then caches it.
