I played some last night going in completely blind. I enjoyed it, but there isn't really a tutorial, just tooltips that come up periodically. Unfortunately my town died after a few hours because I didn't understand I was supposed to be preparing food for as soon as possible (crops grow on a year cycle, so you need the seeds in ASAP). Makes logical sense, but the game doesn't tell you and then I was stuffed.
I think it's totally fun as a sandbox/run-based game, but if you're looking for something more you'll need to wait.
What's the name of this feature for GrapheneOS? I'm not finding it.
