I'm still undecided about selling the game as I first want to see reactions for Phase 1. So when Phase 2 is finished I may sell it as shareware, though I'm not sure about is.

And please note that a patch is underway. The guys over at the german Delpi OpenGL community literally buried me under feedback and it seems that there are some problems and bugs with this release. So I started working on a patch that I may release this weekend (or early next week) that fixes most of the problems.
