Hey, I found your game through this 1up article here: http://www.1up.com/do/feature?pager.offset=0&cId=3177782 and I LOVED it!!
I really look forward to future updates and refinements. A question about the name though, was it at all inspired by this: http://www.squidi.net/three/entry.php?id=22
? (Note, the game described in the link is not an actual game, merely a description of the mechanic.) The gameplay described doesn't really have much in common with your game, but the reason I actually clicked on the link to your game was the name I had read before...

If you aren't familiar with squidi's Three Hundred Game Mechanics project I highly recommend you take a look at it. It's absolutely brimming with game ideas and every one of them has the potential to be an amazing game.
