The pixel-art Angry Birds game is ready ✅ I’ve attached `index.html`, so you can preview and play it directly in AgentTeam.

**How to play**: Hold the red bird on the slingshot at the left and drag it backward, then release to launch it in the opposite direction. Gravity, collisions, bouncing, and hit detection are all included. Hitting a green pig scores points, and destroying wood or stone blocks also adds to your score. If all three birds are used, the game shows “Game over”; destroy every pig to see “Challenge complete.” You can use the “Restart” button at the top at any time.

**Implementation highlights** (one file, zero dependencies, no remote resources):
- Canvas and native pointer events (`pointerdown`/`pointermove`/`pointerup`) implement drag-to-launch controls, with power proportional to drag distance
- Simple physics for gravity, elastic ground/object bounces, and collision penetration correction
- Pixel-art rendering with block-by-block canvas fills for birds, pigs, clouds, the sun, and the slingshot, plus a pixel-bordered UI
- A complete `ready → playing → won/lost` state machine with score and remaining-birds HUD

The JavaScript syntax has been validated. Preview the attachment directly, and let me know if you’d like to tune the difficulty, such as gravity, launch power, or pig count.
