Haha, I like playing games like these while watching Youtube. But the sound of the game was louder than that of the video, and I couldn't adjust the volume of the browser or it would change it of *every* browser window.
I can see why sounds to attacks would become a bit messy once you have a lot of characters on the screen attacking at once. Still though, I'd be curious to see how it pans out if you ever tested it. Best of luck!
