You may want to consider submitting your game to TotalBiscuit's WTF is? series.
He did a WTF is? on your free alpha version, and I'm sure he would be glad to do another for the beta/full game.
Here is a link to his video of the alpha version: http://www.youtube.com/watch?v=kNA6vvEfhoQ
To submit the game, e-mail pr@cynicalbrit.com
Note: I am in no way affiliated with TB nor do I own the game at the moment, only because I have no way to pay for it. I simply think that this is a great way to get your game out there, with almost half a million people likely to see the video.
