Very cool. Some things perhaps should be clearer (I presume Power Up! increases the points you get for each ball you remove/change?) but generally it was a pleasure just to try things, see the results, and try and build a strategy from it. The different sound effects for the different results you could get were a nice touch. Well done :)

Pressing space just locked it up for me... not sure what I'm doing wrong but it definitely wasn't working the way I thought it would.

That was pretty cool.

@devinmoore I've had reports of it not working in FireFox. Chrome may be your best bet.

Tried Firefox (doesn't work), and I tried IE 8, and it doesn't work. I am not going to install Google and agree to their EULA, sorry mate.

Not bad! The only thing was I kept forgetting what pattern did what. It would almost be cool if the game had a legend showing which pattern did what after you "unlock" each pattern. There were just too many to keep in my head.
A solid game concept. Great work!

Pretty cool idea. I was compelled to bust out a pad and pen and log the combinations. Neat; some graphical effects could have greatly increased the experience. However, time was of the essence :P

This locks up my browser completely.

HTML 5, unravelling shit performance that we thought finally forgotten and buried

In Opera, the keys did not just move the selection/activate, they also scrolled the browser window, which was a bit annoying.

Interesting idea.
