Unfortunately the demo is only available in German for now, but a word from the official boards is that the English version will be released tomorrow, but according to the same post, the save feature wont be available in the English version tomorrow since they're still working on it.
You can check the demo out by clicking here, or keep checking back for the English version soon, and remember that the online blueprint demo is only a scratch of the surface of how indepth the game tuning and customization really is.
