Enemy and Respawn task

In this draft i have implemented respawn for the player and made some enemies that damage the player. The player looses 20 health when in contact of an enemy(burger) and looses 50 health if he goes outside the screen. You have 1 extra live and after the health is depleted you will respawn with no extra lives. After this the player will become disabled preventing further playing when health reaches zero or below and no extra life is present.
