From PCGames:
A cozy sandbox survival game where you play a young witch apprenticed to the mysterious Baba Jaga, Reka brings its Slavic folklore inspirations to the forefront in a similar way to how games like Valheim make use of their own fantasy settings – and, yes, you can even build your very own walking house.
As the eponymous Reka, you find yourself deep amid sprawling woodlands, where you have been apprenticed to Baba Jaga, the legendary witch of the forest. You might have come across her in more typically antagonistic roles, whether in folklore or adapted into settings such as The Witcher, but here she’s on your side.
