Astro

WASD to move, C to fire. 

Player has 3 health and 12 ammos, the heart can only be collected if player has less than 3 health

Since this is the web version, the Quit Game button will serve as a restart button. The game will also restart if player has run out of health

Not a good coder, I cant figure out how to change the direction of shooting and the jump animation will keep play until player click next button
