While I'm sure this used to work (or maybe only doesn't work for me at the moment) I couldn't play this game for very long without it crashing. Whenever I pressed the "A" button on my keyboard to fire, it would freeze up and crash the entire page, so that's a real shame.
The art and story looked really cool, so it was disappointing when it didn't run for me. Respond to this if you do fix it, as I will certainly give it a better review after.
