Not to worry-- the game will most definitely be out for free as more updates are made. (Er, until the very end, when it's all finished up it will be only available by being bought-- but that won't be for a WHILE, I promise) The way it works right now is that Patrons get updates EARLY. So basically; there's the free version of the game which will be hosted here and then the "Patreon version" which is just an update or two ahead of the public release.
This is a pretty common way that games (especially porn games) are released right now because it allows for lots of people to play it but also helps keep me getting paid to make it-- so all you need to do is be a little bit patient and the first update will be out within the next few months!
Right now I'm busy working on the Tomai DLC, which is long overdue, and then I'll be working on releasing the 2nd update of this for Patrons, which will push the first update out here for everyone, for free! The second update already has a ton of the dialogue written so I can't imagine it'll take me too long once I'm working on it more full-time.
I do my best to make sure the majority of my work is available for everyone; but at the end of the day it is my job so there's just some stuff I have to do to get by. I appreciate you understanding and how kindly you brought up your question-- it's not something everyone does so I just really appreciate it!
I'm really glad to hear you like my stuff and I hope I can continue to entertain <3
