I just bought the game and I love it ! It'd be amazing if you had a discord on which players could talk about the game / share their worlds and creatures. I'm on The Bibites server and discussion are very exciting.
I think you underestimate the motivation of some people concerning those Alife projects! I mean, the discord doesn't have to be only for those who bought the game, but also for those who are interested. It would be more comfortable than using itch I think.
And if the user gets higher, you'll already have a discord set up!
Haha, I guess I'll keep the idea in mind!
Another consideration is, if I had a Discord up I would probably spend literally every waking second watching it which would not be great for my day job / real life. :)
