🚀 登月着陆Moon Landing
在线登月着陆：用主推进器对抗重力减速，用左右侧推进器调整位置，把着陆器平稳地降落在绿色平台上。下降速度和横向速度都要足够慢才算成功，燃料有限，每过一关重力更强、平台更窄、燃料更少。支持键盘和触屏按钮，3 次机会，记录最高分。Moon Landing online: fire the main engine against gravity and the side thrusters to steer, and set the lander down gently on the green pad. Both descent speed and sideways drift must be low enough, fuel is limited, and every level brings stronger gravity, a narrower pad and less fuel. Keyboard or touch buttons, three tries and a best score.
↑ / W 主推进器，← → / A D 侧推进器；手机按住下方按钮。左上角速度变绿才能安全着陆。P 暂停，N 重开。↑ / W main engine, ← → / A D side thrusters; on a phone hold the buttons below. Land when the speeds top-left are green. P pauses, N restarts.
玩法说明与常见问题How to play & FAQ
「登月着陆」怎么玩？How do I play Moon Landing?
着陆器一直受重力往下加速。按住 ↑ 点燃主推进器减速，← → 左右平移。必须整个着陆器都在绿色平台上，并且下降速度 ≤ 34、横向速度 ≤ 22 才算成功；落在山坡上或速度太快会坠毁。剩余燃料越多，着陆得分越高。Gravity keeps pulling the lander down. Hold ↑ to fire the main engine and slow down, and use ← → to slide sideways. The whole lander must touch down on the green pad with descent ≤ 34 and drift ≤ 22; landing on a slope or too fast is a crash. The more fuel you have left, the more a landing scores.
燃料用完了怎么办？What if I run out of fuel?
燃料耗尽后推进器失灵，只能靠惯性下落——提前规划，不要一直按着推进器。With no fuel the engines stop and you simply fall — plan ahead instead of holding the thrust.
为什么速度数字是红色的？Why are the speed numbers red?
红色表示此时着陆会坠毁，变绿说明速度已经足够安全。Red means touching down now would be a crash; green means the speed is safe.
