Shoot 'em! Up!

Here are a few screenshots of the first game I'm working on.  It's build in XNA, and is a 2D, side-scrolling shoot-em-up, thus far based around the powerpuff girls.  So far I have a nice flexible framework for adding badguys, powerups, etc, some fairly dodgy collision detection (fixing it soon, I promise!), parallax scrolling backgrounds, and a pretty rough looking menu (which I choose not to show here...).

But still, Powerpuff Girls, Mojo-jojo and floating brains - what more could a good game need?
