Woohoo I escaped the lab! This game is really great. From the art to the gameplay, it is the product of lots of good design decisions. I really liked how the bullets only moved when your characters did. I would suggest considering adding lives and checkpoints just because their didn't seem to be any real drawback to dying other than having to start the level over. But for the sake of letting people get a real taste for it I think you struck a great balance.
