Just downloaded the "Free" version and let me tell you, it's not good. Not good for the simple fact that it's SUPER short. Granted you just released this game and I don't know about the paid version, but releasing a "Free" version and it being so short is a little ridiculous. It's so short it's not even a "Demo."
The way you have it set up literally makes it seem as if both versions are the complete titles, but the paid version contains EXCLUSIVE content. In all actually, (as of now) that's clearly not the case.
Stating that it's v1.0 ON release suggests that it's a ready to play title and contains the base content. If that's not the case, then you need to update the version code and this very page. As far as I can tell, this is misleading.
