## Best Practices

### Collectible Placement

- Reward exploration with hidden items
- Place valuable items off the main path
- Use materialization to gate progression

### Information Delivery

- Use Signs for detailed/optional information
- Use Explainers for required tutorials
- Use Communications for story updates

### Collision Design

- Align walls with visual boundaries
- Test player movement thoroughly
- Leave clear walkable paths

### Minigame Design

- Keep interactions simple and intuitive
- Provide clear instructions
- Balance difficulty with rewards
