Using the pre-provided phaser.min.js (global Phaser), build a top-down alien shooter: move with WASD, aim and fire at waves of advancing aliens, with health, score, and increasing difficulty. Use ONLY procedurally generated graphics, no external image or audio assets.

I'm setting up a Phaser game in a single HTML file and need to verify the Phaser library is available.

Now I'm going to start building out the game.

The regex caught the inline script but missed the src attribute one. Let me verify the JavaScript syntax is correct.
{"command":"cd /workspace && node -e \"\nconst fs=require('fs');const h=fs.readFileSync('index.html','utf8');\nconst js=h.split('<script>')[JS syntax OK
Done. `index.html` is a fully self-contained top-down alien shooter. **Features:** - **Movement:** WASD with momentum (acceleration + drag) - **Aim & fire:** mouse aims the player; click/hold to shoot bullets toward the cursor - **Health & score:** HP bar (color-shifts as it drops), live score counter - **Waves & difficulty:** each wave spawns more, faster, tougher aliens; three alien types (bigger = more HP + score), tankier enemies and quicker spawns as waves climb - **Game feel:** procedural muzzle flash, particle explosions, camera shake/flash, twinkling starfield, wave banners, and an R-to-restart game-over screen **All graphics procedural:** player, three alien variants, bullets, sparks, and stars are drawn at runtime via Phaser `Graphics` → `generateTexture`. No external images, audio, or network requests — only the local `phaser.min.js`. JS passes a syntax check and the file loads Phaser with a plain `<script src="phaser.min.js">`.
