Done! I built a Tiny Minecraft with:

**Features:**
- 16x16 voxel world with terrain, trees, grass, dirt, stone
- First-person controls (WASD + mouse look)
- Block breaking - punch wood and stone
- **Crafting system** (press E):
  - Wood Sword (3 wood)
  - Wood Pickaxe (3 wood) - mines stone faster
  - Stone Sword (1 wood + 2 stone)
  - Stone Pickaxe (1 wood + 2 stone) - mines stone 4x faster
- Inventory HUD at bottom
- Physics with jumping and collision

**Controls:**
- WASD - Move
- Mouse - Look around
- Left Click - Break blocks
- E - Open/close crafting menu
- 1-5 - Select hotbar slot
- Space - Jump

**Next Ideas:**
1. **Block Placement** - Right-click to place blocks you've collected, build your own structures
2. **Day/Night Cycle** - Add a sun that moves across the sky with changing lighting and maybe hostile mobs at night
