Prompt for this run
Build a playable top-down alien shooter using the provided Phaser library. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. Use the provided `phaser.min.js` (global `Phaser`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Move the player with WASD, aim toward the mouse pointer, and fire with the left mouse button. Display the controls on screen. - Start with a playable arena, a living player, and a first wave of aliens that advance toward the player. Player shots damage aliens; contact with aliens damages the player. - Display health, score, and wave number. Award points for kills. After a wave is cleared, start a harder wave by increasing enemy count or speed. - At zero health, stop gameplay and show a game-over state with Restart. Restart restores health, score, and the first wave. - Generate all graphics procedurally with Phaser Graphics or generated textures. Do not use external image or audio assets. Verify: Test movement, aiming, and firing in the opening encounter. Check that shots travel toward the pointer, aliens advance toward the player, and a projectile hit produces visible feedback. Reload and check the initial health, score, and wave.

Diagnosing button click coordinate mismatch due to overlay scaling and confirming R key restart works reliably.Verifying reload resets initial state and assessing movement proof limits from key input constraints.
Restart via keyboard works perfectly. Let me confirm the fresh-load state one final time.

Done — `index.html` is saved (19KB, local `<script src="phaser.min.js">`, no external/CDN requests). **What I built:** top-down arena (960×600, grid + starfield + neon border) with procedurally generated textures (player, 3 alien types, bullet, particles). WASD/arrows move, mouse aims (player rotates to pointer), hold left-click fires toward pointer. Aliens spawn at edges and chase the player; bullets damage aliens (white flash + sparks + "HIT" text + shake), contact damages player (red flash + shake + knockback + i-frames). HUD shows health bar, score, wave, kills + on-screen controls bar. Kills give 100/150/300 pts + wave-clear bonus; next wave increases count and speed with new enemy types. At 0 HP physics pauses and a GAME OVER overlay with score/wave/kills + RESTART button (also `R`) appears; restart resets health/score/wave 1. **Actually checked in browser:** - Initial load: 100 HP, Score 0, Wave 1, live player center + 6 wave-1 aliens, controls visible, no console errors. - Aim: click toward right alien rotated gun from up-left to right. - Firing/kill: drag-fire toward right killed an alien → Score 100, Kills 1; aliens visibly converged on player across frames. - Contact damage: health fell 100→64/76 during brawl. - Game over: health hit 0 → overlay "GAME OVER Score:100…" with RESTART. - Restart via `R`: restored 100 HP / 0 score / Wave 1 with fresh aliens. - Reload: back to 100 HP / 0 / Wave 1 cleanly. **Remains unverified:** sustained WASD displacement (key tool only taps; code sets 300 px/s velocity), long-run wave-2+ scaling, and HTML Restart button click (coordinate mapping missed in harness — `R` key path verified, button uses a standard click listener and should work in a real browser).
