玩法说明与常见问题How to play & FAQ
「洞穴飞行」怎么玩？How do I play Cave Flyer?
飞艇会自动向前飞，你只需要控制高度：按住时向上加速，松开后受重力向下加速。洞穴的上下岩壁起伏不定，通道会随着距离慢慢变窄，中间还会出现石柱挡路。要领是轻点、短按，让飞艇保持平稳的波浪形路线，而不是一直按住或一直松开。The airship flies forward by itself and you only control the height: holding accelerates it upwards and releasing lets gravity pull it down. The cave roof and floor rise and fall, the passage slowly narrows with distance, and rocks appear in the middle. The trick is short, gentle presses that keep the ship on a smooth wave rather than holding or releasing for long.
总是撞到上面怎么办？I keep hitting the roof — help?
飞艇上升有惯性，看到要撞顶时要提前松开。试着用很短的点按来微调高度。The ship carries momentum, so let go before you reach the roof. Try very short taps to fine-tune your height.
会越来越难吗？Does it get harder?
会。飞行速度和石柱出现的频率都会逐渐增加，洞穴通道也会越来越窄。Yes. Speed and the frequency of rocks increase gradually, and the passage keeps narrowing.
