Are you against an open alpha? I downloaded the alpha, because I've been really very impressed with what I've seen and wanted to get a closer look, but apparently I need a key. Could I maybe receive one?
The game looks fantastic and very well designed. Incredible work, and I hope it does very well.
Thanks!
Well, let me put it this way - after about a year and a half of work and spending oodles of my own money to make things happen, I'd like to maybe, just maybe, make a little of it back

In addition to getting player feedback, the alpha is also about financing continued development.
I'm not opposed to a free demo type of thing - in fact, you can count on a demo being out when the game is closer to being feature complete. That's probably going to be a while, though.
