I decided to update the demo since I made a lot of small improvements that changed the way the skull bounces off the paddles.

• When you hit a paddle, the angles of the skull are narrower so you have more control
• The power ups are moving slower, giving you time to avoid or catch them
• I added instructions on how the navigation system works
• Several small improvement and optimization  in overall gameplay

Let me know if you find any bugs or weird things!
