They have been working on the game, this is just the public release version, patreon players normally have the newest builds
Yeah that's understandable, but I also get the impatience since it's been just about 9 months since the last public release.
How regular are the updates on Patreon? I might genuinely join it. I'd say I'm usually really patient with game updates to avoid spending money, but I genuinely really love this game and waiting 9 months for an update is crazy even for me.
