Hello there!
I recently developed pixelMonstrosity, a 2D shooting game with black and white graphics.

Here is the link: http://scratch.mit.edu/projects/16873071/

To play, simply dodge the monsters and grab more health and ammo to keep you alive.
control: WASD to move, mouse aim and click to shoot.
Check it out.
Enjoy!

P.S. My high score: 1105 kills. Try beat me!
