Quick bug fixes after the jam time, there was also some performance enhancements and some simple game rebalacement

Fixed:

• End stage screen stuck after non intentional death at the end of the second stage
• Foods been created and not deleted causing the game to lag a lot in the third stage
• Third stage music not looping
• Be able to die at the end of the second level, replay it and skip the third level
• End stage screen text showing "+1 Life" instead of "+2 Lifes
• Some other grammar mistakes

Rebalancement:

• Added little coyote jump
• Made food easier to see
• Deleted and annoying enemy at a bad positioning
• Decreased shooting cooldown for player
