Apparently this is out now, and my impression is it happened today. I bought it without trying the demo just because I think I've heard that it's good from someone on Twitter or something. It's about exploration, which I tend to love, and it's pretty cheap (8 credits) and it's available on both Windows, Mac and Linux and the site lacks a favicon.
