阿飛 AFEI
Launches 10 November 2026 · PC · Casual, Indie, Simulation
A fruit fly in a glass box on a windowsill. A small, slow game: place fruit, tap the glass and watch it walk, eat and take off, across 20 tasks. Its brain is a simplified model built from the published wiring map of a fly's central nervous system. All movements are assisted by code.
Story
One fruit fly. A brain model you can watch. AFEI is a small, slow observation game. One fruit fly lives in a glass box on a windowsill. You place fruit and tap the glass, then watch what the model and the physics body do. There are 20 tasks, most of them short; once they are done, there are no new goals. What you do Place fruit. Up to three pieces: strawberry or banana, from fresh to mouldy, close to the fly or far away. Fruit ripens in real time (over hours). Tap the glass. Code sends a synthetic looming signal to the fly's looming-detector neurons. The model's take-off neurons trigger the take-off; code sets when a take-off can start and assists the jump and flight. Open the brain map. Show the whole central nervous system, the brain, or the smell path. Fibres are drawn from measured neuron shapes (simplified); the glow is the model's firing at that moment. Look closely. Orbit, zoom and follow the fly, and give it a name. Complete 20 tasks. From "Watch it eat" to "Weaker fruit reached first". Each task gives a card with one sentence on what the model does and what the code does. Finish all 20 for a full clear. The science, plainly Afei's brain is a leaky...

The science, plainly Afei's brain is a leaky integrate-and-fire (LIF) model of all 165,122 neurons and about 25.6 million neuron-to-neuron connections in the Male CNS v1.0 connectome, the published wiring map of one male fruit fly's brain and nerve cord.
