Seeds of Resilience, a turn-based village building survival game from Subtle Games and Goblinz Studio is leaving Early Access on June 13th.
It just recently had a pretty big update too, adding in actual missions to do so it's not just a basic sandbox village builder with you battling against the elements. The new missions serve as a better introduction to the game too, so it's not as confusing as it was when I tried it some time ago. There's currently only 7 missions to go through, with another 10 planned for the full release.

The survival mode now does also have an actual objective too, with you needing to build a ship so your people can actually leave the island giving it more of an actual purpose to it. It's an interesting idea, one I quite like but I do need to play plenty more of it to get a full opinion. With the full version coming soon, I will be taking a proper look when it's finished to really see if it's worth your time.
It already has Linux support and it's available right now on itch.io and Steam.
