No worries, I played full games there that were shorter that Dusken Blades already is, and like half of games there are in alpha or beta or just abandoned outright (that's just the reality of making games for free, I guess).
The point is, people there are already used to trying unfinished games if they look promising. And considering the theme of the game, I think it will fit there, that's why I mentioned the site here.
