MH - updating the app so that the players has a fire rate. (Before the player fire rate was based on when the missile was offscreen but now it’s just a fire rate control and more than one missile can be on screen at the same time.)
MH - Big update that adds the concept of a game over state. When an alien collides with the player the game state is set to game over and all animations are stopped and on the next player touch it returns to the game menu screen.
