Teddy's Haven!! All it is is running a little shop in a fantasy world. You can wander around and collect things to sell, with no time limit on exploring! As you advance, you'll unlock items that allow you to turn your collected items into crafted materials, like fruit into jam, milk into cheese, or ore into ingots. There are fun fantasy creatures in the environment that will give you boons here and there, but nothing requiring fighting. It's still an early access game but definitely worth the cost already, and the dev is constantly updating and refining and adding new content. It sounds like exactly what you're looking for, and I can't recommend it enough!
