The user wants me to build a complete, playable Tetris game as a single HTML file. Let me create a comprehensive implementation with: 1. All7 tetrominoes (I, O, T, S, Z, J, L) with proper colors 2. Canvas-based rendering 3. Rotation mechanics (wall kicks) 4. Line clearing with animation 5. Increasing speed (levels) 6. Next-piece preview 7. Score system 8. Controls: arrow keys for movement/rotation, space for hard drop Let me write this all in one file.

The file has been written. Let me verify it exists and is valid.
The Tetris game is built and ready. Here's what's included: **All 7 Tetrominoes:** I, O, T, S, Z, J, L — each with its classic color **Gameplay Features:** - **Rotation** with SRS wall kicks (including I-piece special kicks) - **Ghost piece** showing where your block will land - **Next-piece preview** panel on the right - **Hard drop** (space) and **soft drop** (↓ arrow) - **Line clears** with a white flash animation - **Increasing speed** — drops ~70ms faster each level (caps at 50ms) - **Scoring:** 100/300/500/800 pts × level for 1/2/3/4 lines, 2pts per hard-drop cell, 1pt per soft-drop cell - **Levels up** every 10 lines cleared - **High score** persisted in localStorage - **Bag randomizer** (7-bag system) for fair piece distribution - **Pause** with P key **Controls:** | Key | Action | |---|---| | ← → | Move | | ↑ | Rotate | | ↓ | Soft drop | | Space | Hard drop | | P | Pause |
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.

EVALUATION
Only a static Tetris start menu is shown; clicking Start Game was never triggered, no gameplay visible.

MEASUREMENTS
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.
