代码： 全选
改進：
一，排行榜應有序號1.2.3……。
二，當網頁打開時，將自動生成一個用戶名（排行榜最大一個guest加1）。這個名稱將不能更改。
三，遊戲結束時將顯示當前的排名情況，並自動保存至排行榜，同一個guest將只收錄最高分。
四，如果超越了相同用戶名的最高分，則顯示「創造歷史最高分」，如果沒有，則顯示「歷史最高分為…」。

改進：
去掉排行榜，當前會話的最高分數及其用時將記錄在一個var變量中，當頁面刷新則重新開始計。
如果超越了最高分，則顯示「創造歷史最高分：…」，如果沒有，則顯示「歷史最高分為…」。
增加函式，使外部（例如通過iframe）能夠探知遊戲是否結束以及結束後的分數和用時。代码： 全选
> OK let me now produce the final HTML. I'll be comprehensive and make sure everything works.
> Let me also fix a small issue: the original code uses `ctx.roundRect` but that's a method on CanvasRenderingContext2D that might need a polyfill in some browsers. Actually, `roundRect` is supported in Chrome 99+, Firefox 112+, Safari 15.4+. It should be fine for modern browsers. The original code used it so I'll keep it.
> Now I'll write the full HTML.
This is a complete HTML document for a "纸飞机极速下落" (Paper Plane Speed Drop) game. It's a side-scrolling avoidance game where you control a paper plane falling through obstacles, built with Canvas and SVG for a pseudo-3D effect.
