Hey,
If you sign up for the mailing list at the bottom of this page here I'll just email you a download key when I push out the next update which should be in the next week or two.
I'll be opening the game for anyone to download again as well, but it's just in fixed quantities (like 25 or 50) and I don't know if those will go quickly or not. I put a limit on the number of downloads available because I wanted to sell the game at some point, but I'd still like people to be able to play it and test it out in the meantime. Signing up for the mailing list should get you a key that will last throughout all the updates.
