This assignment will build on the $$Canvas$2$D Asteroids$$ example which was discussed in class. You

must use this code as a starting point and build on it rather than starting with your own code base.

$$ Add collisions $($so that the player can be killed when hitting an asteroid$).$ The classic asteroids

game did not have collisions between asteroids.

$$ Add bullets $$ so the player can shoot the asteroids. When shot, large asteroids split into small

asteroids, while small ones are removed from play

$$ Add a scoring system and lives $($the player gets $3$ lives before the game is over$)$

$$ Add some kind of visual explosion effect when the player is killed

$$ Add a levels system $$ so when all asteroids are destroyed, a new larger group of them is

spawned

$$ Add alien spaceships which fly across the screen from time to time if the player is being slow

completing a level. These spaceships shoot at the player as they cross the screen.
