Bugfixes, balancing and new tracks in the radio

We have made some adjustments to the game in response to the feedback we got during the Nordic Game Jam showcase! We appreciate all the feedback we got!

• Added 3 new songs to the radio. Let us know if you recognize them!
  
• Added a delivery counter so you can keep track of how many yummy pizzas have been delivered.
• Adjusted some things to make the game easier at first, but harder when playing longer.
• Made roads bumpier.
• Fixed bug where restarting the game allowed the player to drive with the engine off.
• Reduced some annoying screen effects for better visibility.
