Thanks for the reply!
Right now on itch.io at least, the public version Starbreed v0.4.4 PC.zip is out for free. And I know the latest build is on Patreon at the moment.
How much would the full release on Itch.io be?

There is no determined price yet, but the full game will be launched on Itch.io as well. There is also a good chance the free demo will be updated in the near future, though there probably won't be toooo much more content. It is mostly to bring the official demo up to the current version in terms of function, and updated assets (Like UI, etc)., but we'll see.
