Ideas to extend the application:
- Button to start/pause the game
- During game play at random places put food, when snake eats it, it becomes larger (instead of the current " F-button-hack")
- Snake touches border -> loose life and restart
- Extend the game with other electronics:
- RGB LED (strip?) to visualize eating/dying/...
- Speaker for sound effects on eating/dying/...
- Extra buttons for ... ?
- IMPORTANT: this example project should not become too big as it would then be hard to use it as a base for other users. Please keep this in mind, and when you want to "go crazy", please extend further in a separate repository.
