## Resolved Issues
1. Menu Interaction
   - Issue: Menu items not responding to clicks
   - Solution: Added proper mouse click event handling in game loop
   - Solution: Fixed menu item highlighting and selection state

2. Snake Movement
   - Issue: Rapid direction changes causing self-collision
   - Issue: Missed inputs during quick turns
   - Solution: Implemented input buffer system
   - Solution: Process one direction change per grid movement
   - Solution: Store up to 2 pending direction changes

## Next Steps
1. Implement AI snake movement
   - Set up ML training environment
   - Create neural network architecture
   - Train initial model
2. Add high score system
   - Implement score persistence
   - Add high score display
3. Add visual and sound effects
   - Implement basic animations
   - Add game sounds

## Known Issues
- None reported

## Future Considerations
- Multiplayer support
- Additional game modes
- Custom themes/skins
- Achievement system
