You Have One Shot At This

Shoot all enemies. Seems simple enough, until you realize you have nothing but a single bullet left in your revolver.

Note: if the controls don't seem to work at first, try clicking inside of the iframe that my game is contained in. That fixes the problem like 90% of the time.

Also note: I tried having the bullet be quick. I failed. 

Also also note: due to some quirkiness with  JavaScript I couldn't get the assets to load. That's why there's no background music, and that's why I had to resort to placeholder graphics.  ¯\_(ツ)_/¯
