In what feels like a years long quest to find another game truly like Stardew Valley, I think I've finally found one that is close with Little Witch in the Woods.
Early on it's very linear, essentially an hour and a half long tutorial. There's too much dialogue and what's here is very odd and amateurish (or maybe I'm just too old), but it's still early access so hopefully they hire a scribe to punch it up some while also trimming down some unnecessary lines. But the rest of the gameplay is great. Study the world around you, craft witches brews and treatments, chase critters for their goodies, complete quests for villagers, etc. Nice chill vibe, great pixel art and retro music.
It's still rough around the edges and not nearly as expansive as Stardew (no surprise), but there's a lot of potential here and definitely a game to be enjoyed.
