playaility: feedback

[kubamarkiewicz]

feedback: player should know if he win or not. We can save the highest score and in the moment when the player beats the record we can play a special sound and display "You have beaten the last record!". And at the end of the game: "Your score is: 123. Congrats, you got the highest score!". Or if you don't win: "Your score is: 10. The highest score is 123. Try again!". Or we can display the record all the time.
