Fruit Fly World is a single-player lineage roguelite. You forage under pressure, read the predator's committed lunge, and trigger the Giant Fiber escape when the response is ready. It runs full-screen on this site — the research pages around it explain what it is modelling.Fruit Fly World 是一款单人血统 roguelite。你在压力下觅食，读懂捕食者锁定的扑击，并在 Giant Fiber 响应就绪时触发逃脱。它在本站全屏运行；周围的研究页面解释它在模拟什么。

Short decisions.
Longer lineage.短暂的决定，
更长的血统。
Every generation turns a few seconds of reading and action into a consequence carried forward. The model is inspired by biology, but the rules are explicit and playable.每一代都把几秒钟的观察与行动变成可延续的后果。模型受生物学启发，但规则明确且可以游玩。
FORAGE觅食
Move toward sugar, yeast, and rot. Food becomes energy, and your position changes the risk of the next moment.向糖、酵母和腐烂物移动。食物会转化为能量，而你的位置会改变下一刻的风险。
MANAGE ENERGY管理能量
Energy is converted into eggs automatically. High-value food can leave you exposed, so the safest route is not always the richest one.能量会自动转化为卵。高价值食物可能让你暴露，所以最安全的路线不总是最丰盛的路线。
READ THE LUNGE读懂扑击
The predator approaches, then commits to a trajectory. Watch the approach and wait for the Giant Fiber response to become READY.捕食者先靠近，再锁定轨迹。观察它的接近，在 Giant Fiber 响应变为 READY 时做出判断。
ESCAPE逃脱
Press Space or tap GF ESCAPE at the right moment. A short decision window determines whether this generation survives.在正确时机按空格或点击 GF ESCAPE。短暂的决策窗口决定这一代能否活下来。
CARRY IT FORWARD延续血统
At generation end, compare eggs with the wild type and choose one mutation from a three-card draft. The next fly inherits the consequence.一代结束时，将卵与野生型比较，并从三张突变卡中选择一张。下一只蝇会继承这个后果。

Not a complete brain.受回路启发，
不是完整的大脑。
The game uses a simplified escape model and research-informed names as design references. It is not a complete fruit-fly brain, a complete connectome runtime, or a claim about animal behavior.游戏使用简化的逃脱模型，并将研究中的名称作为设计参考。它不是完整的果蝇大脑、完整的连接组运行时，也不是对动物行为的宣称。
