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!).

When this is released where do you plan on releasing it?

P.S. This is most likely one of the best games I've played.
