The developer, Emilios Manolidis, released the game on Steam in February with a Linux version being added a few days ago. The release that adds Linux support also expanded the dialogue options, expanded the in-game help and fixed some bugs.
It has the features you might expect like growing crops, raising animals, crafting and cooking, day/night cycle, seasons and so on. However, it's on the darker side as not everything is as happy as it seems on the surface.
Honestly, it looks like a really sweet game. Quite a bit like Stardew of course, although Stardew does take heavy inspiration from other games before it so it's not really copying it—just to be clear on that. I'm simply making the comparison since others will as Stardew made it popular again.
