  1. The player will lose one life.

  2. An animation will play

  3. A sound will play.

  The player starts the game with 10 lives. If the player's life becomes 0 before the skier reaches the bottom, the skier crashes and the game ends. If the skier reaches the bottom the player gains one level.

  You need to design the algorithm.
