Score Sprite

The next two sprites show the score of the player. As soon as the bird crosses the hurdle of pipe the score should increase by changing the next costume. We have used two numbers of sprites to show the score in two-digits. You may notice that we have used numbers as costumes, you can simply display the score in the variable too.number sprite
