Not Quite Space Invaders

It's up to you to defend the bottom half of the screen.
Space to shoot, arrow keys to move, you can take three hits.

What is happening is this, you have in the Bullet act() method two method calls, each which could remove the bullet from the world. If the first one removes the bullet, then there is no world to check location of it, or any other object. Probably best to check collision of bullet with invader in the invader class, and just check for worldedge in the bullet class.
