Fixed three issues:

1. **Movement**: The SDK joystick `MOVE_Y` positive = forward, but the code was treating negative as forward (keyboard convention). Now uses `moveZ` with correct sign — positive = forward, negative = backward.
2. **Look controls on mobile**: Added a deadzone check so the camera only rotates when the look joystick is actually being used.
3. **Break/Place**: Added `!!` coercion to prevent truthy/undefined edge cases with the shoot/action toggle tracking.

**Next Ideas:**
1. **Add block textures** - Replace solid colors with actual pixel-art textures for a more authentic Minecraft feel
2. **Infinite terrain** - Generate terrain chunks dynamically as you move, so the world feels endless
