Aliens should randomly shoot.

The frequency of the shooting should increase with the levels.

Avoid friendly fire. Aliens should not shoot if there is another alien below them.

When an alien shot hits they player he should lose a life.

When lives is zero, show the game over screen.

The title screen should allow for starting a one or two player game.

In two player mode, when one player dies, then it's the other player's turn.

This will require multiple PlayScreen instances. Only one will be active at a time.

There should be a delay when changing players and display a message that it's the other player's turn.

When an alien or player shoots one of the shields it should get a hole in it.

This is waiting on a Stamp Mask feature in the engine.

Keep track of the high score.

Show this on the title screen and game over screen.
