Cosmic Courier (HTML5 Arcade Game)

A complete HTML5 arcade game in a single file. Pilot a courier ship through an asteroid field: dodge falling asteroids, collect glowing cargo pods for points, survive as long as you can. 3 lives, rising difficulty, score and best score, WebAudio sound with a mute button, keyboard (arrows / WASD) and touch-drag controls, mobile-friendly canvas, game-over screen with instant restart. Best score is saved in the player's own browser only — no account, no server, no leaderboard, no purchases inside the game. Telegram WebApp-ready (guarded API calls: ready/expand, haptics) — outside Telegram it plays exactly the same. No backend, no external dependencies except the optional Telegram script, which the game works fully without.

What's inside: index.html (the whole game: canvas, controls, sound, overlays, best-score save, guarded Telegram WebApp support); README.md (how to play and host it).
