Build a playable Tetris on a canvas with all seven tetrominoes, rotation, line clears, increasing speed, a next-piece preview, and score.

The user wants me to build a playable Tetris game in a single HTML file with:
1. Canvas-based rendering
2. All seven tetrominoes (I, O, T, S, Z, J, L)
3. Rotation system
4. Line clears
5. Increasing speed as the game progresses
6. Next-piece preview
7. Score tracking

Let me create a complete, self-contained HTML file with all the game logic.
write /tmp/ws/index.html (17244 bytes)

I've created the Tetris game. Let me verify that the file exists and check its contents to make sure everything is correct.

I've created a fully functional Tetris game in a single self-contained HTML file. The game includes: **Features:** - ✅ All 7 tetrominoes (I, O, T, S, Z, J, L) with classic colors - ✅ Piece rotation with wall kicks (attempts to nudge piece if rotation hits a wall) - ✅ Line clearing with scoring (100/300/500/800 points for 1/2/3/4 lines) - ✅ Increasing speed (level up every 10 lines, dropping interval by 100ms per level, min 100ms) - ✅ Next-piece preview panel - ✅ Score, level, and lines tracking - ✅ Game over detection and restart functionality - ✅ Pause feature (press P) **Controls:** - **← / →** - Move left/right - **↑** - Rotate - **↓** - Soft drop (+1 point per drop) - **Space** - Hard drop (instant drop, +2 points per row dropped) - **P** - Pause/unpause The game has a retro cyberpunk aesthetic with neon colors, glowing effects, and a clean UI. The board uses a 10x20 grid rendered on a canvas with no external dependencies.

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
