It will cost money, yes, although we don't know at what price point yet. In the meantime, our supporters on Patreon have access to in-progress game builds as they are done, and will ultimately get a copy of the game when it's done (although that is a ways off yet!).
Viewing post in When this game is complete will it cost money?
For the near future the free demo will include Chapters 1 & 2 for each of the three MacLeod sisters. Grace's Chapter 2 is available right now as a Steam Demo exclusive, although we will migrate it over here as well shortly. Until then, you can grab it here! https://store.steampowered.com/app/1232870/Changeling_Tale/
Thank you. I am not shure yet, but once the game if finished, i might buy it it looks verry good, and has an interesting story. I like games with a bit of everything (horror, fantasy, nsfw, drama, comedy,... etc) and your game is exactly what i am looking for. A bit of everything, "a slice of life" as some call it.
