Pixel Prototypes update

Hey 🐊💕
Another update on my prototypes!

Here are the changes:

Canyon Race

- Basic UI
- Sounds and music
- Race is not infinite anymore
- Menus and track selection
- Second track! AI is not very well done on it atm.
- Acceleration is now always on. Go fast! No brakes!

Overall

- Better musics and sounds
- Better menu flows
