Built a Minecraft MVP with:

- **First-person voxel world** (32x32x32) with procedurally generated terrain including hills and trees
- **5 block types**: Grass, Dirt, Stone, Wood, Sand
- **Place & break blocks** with left/right click
- **Physics**: gravity, jumping, collision detection
- **Block highlight** showing which block you're targeting
- **Hotbar** with scroll wheel or 1-5 keys to select blocks
- **Particles** when breaking blocks
- **Synthesized audio** for place/break sounds
- **Fog** for atmosphere

**Controls**: WASD move, Space jump, Mouse look, Left click break, Right click place, 1-5/Scroll select block.

**Next Ideas:**
1. **Crafting & Inventory** - Add more block types (glass, brick, water) with a full inventory screen and crafting recipes
2. **Day/Night Cycle with Mobs** - Animate the sun across the sky, add darkness at night, and spawn hostile mobs that chase you
