Will the full version be free when it comes out like the first and will the demo be free and will it be released on steam

I don't believe so, I'm pretty sure I saw changer mention during the initial announcement that the full version won't be free.

Yeah, the full version will not be free. Unfortunately free releases have kind of fallen off in sustainability. But as I don't like to gate off content completely I am planning to have a demo that includes all the Elf Kingdom girls.
