when will it update and will it be free or pay?
The game will be free for ever. (That's why I opened a Patreon page for anyone who wants to collaborate).
Next Wednesday I'll post a little sneak peek of version 0.1, I guess it will be available at the end of August for Patreon subscribers and by mid-September for the public version.
Until then I'll keep working, there's a lot to do.
