The constant tutorials can be overwhelming, yeah. Just know, the game is (usually) many layers, and you can still have a blast ignoring the basic tutorials and just turning your brain off and smashing stuff, or you can focus up and hit the lab to really refine how you use a particular weapon or practice strategies against a specific monster, kinda like a fighting game.
Not to belittle Stardew, a game I adore, but Stardew is itself very much cribbed, as a desperately needed spiritual successor to the Harvest Moon/Rune Factory games. I don’t intend on checking out fields of mistria so I’ll just take your word on the rest.
