Hey, great question and good timing.  I'm going to be pushing a new build with some updates, fixes, design improvements, etc. in the next couple of weeks.  I'm going to be emailing people the game to test out those updates and I was going to just email everyone that signed up on the mailing list.

The link for the mailing list is at the bottom of this page:

If you throw your email address on there I'll just send you a download link to the game in a couple of weeks when I push the build.
