I can't assure that your game will be a bestseller or that you would sell thousands of copies, but the thing I'm sure with is that your game is going to mark and go with the new generation of indie Rpgs. I love Everhood, I listed to the soundtrack regularly and also I see a lot of fandom and good comments on the discord.
Maybe the part of being famous, and makint a lot of noise on the internet, etc, could put you in a hard situation, but well, it's part of the process, to have that in mind, to not sell even, it's a pretty undertrandable thought.
The only thing I can assure is that there's going to be a lot of people like me that would play, love and share the game experience. You're making something really different, interesting and inspiring. I see a lot of potential on being a cult game or something like that.
So, besides marketing and that kind of sh*t you have to make in order to get known and etc, the real work, as in the case of most succesful indie games, is made by the fans and the community. You both been working a lot on this. Make your last effort, make noise, do whatever you need to make this something that is worth in the economic part. Then, it's our turn, to make a bigger a bigger community, to tell our friends, to play and enjoy, and make fanart.
As a novel developer, your game has been a lot of inspiration, and at least, I can tell, since the day I've played Everhood I knew that you archieved something I couldn't even imagine at the beggining. Now, I want to be part of that movement; a new generation of indie RPGs that gives the player a new perspective on how can things be done and how much the genre can give.
I send you good vibes!, goodluck. As soon as Everhood's out, You'll have my money and my time.
