So Hey Guys

Aim of the game is to jump over the balls.

What i need help with: when the ball hits the player i want the player to "die" maybe a new screen come up saying "Died. Try again"
and on the top left of the screen i would like a counter to how many balls the player has jumped over. like Score: +(Balls jumped over)
