@Reconnoiter: That's a nice idea, thanks. I will give it a try.

@JibbSmart: Thanks a lot for that highly informative post! I see, less is more, I didn't even think about selling it myself/ on my own homepage. However, although they seem to be your biggest points and "regrets", I cannot sell it or make a demo available before a potential Steam release/ during Greenlight because of the type of planned promotion. I realize that my approach is risky and I'm potentially losing some sales there but I simply have to try to go big or go home.

@tolu619 (below): Estimated release window is November-December (I hope!).
