Mobile games, in my experience actually tend to have the most success. Surprisingly, the production value of mobile game anime adaptations tend to be the highest, with a solid plot that the original game might not have been able to produce in it's mobile medium. Examples can be Rage of Bahamut Genesis (only season 1 let's be honest here) or Magatsu Wahrheit: Zuerst.
Tensui no Sakuna hime? It's a console game. Still, I don't judge. The first six or so episodes were good, especially the first 3 or so. It's about farming on a remote island, with a main character that acts spoiled, but slowly comes to age as the story progresses. Whether it be doing minor chores, taking on major responsibilities, or acting as a mediator, Sakuna-hime goes from a pampered spoiled god to someone that is shouldered with a bit of responsibility as a Goddess of Harvest. Sakuna-hime is a great character that's multifaceted and experiences many dynamic changes due to the challenges and hurdles she's forced to confront.
However, that's where all the magic stops happening. When the show becomes less about character development and farming, then it starts going downhill. Suddenly, a show about farming and developing land and character interaction becomes some third rate shounen anime about beating the evil god. Of course, this theme about demons looming around is certainly a theme that was always behind the scenes, but to so suddenly only focus about fighting was a wrong move. You're subject to the most one dimensional villains with self-righteous dialogue from Sakuna-hime and the rest of the cast that it's sickening. Yet another cliche-filled dialogue about how "we have to stop the cycle of hatred," and yet none of the main characters are forced to make a difficult moral decision. Rather, despite letting go villains and evil-doers constantly, the issue resolves by itself. By "forgiving everyone," Sakuna-hime and her people are able to still easily be absolved of any consequences due to plot armor. The final boss is similarly boring plot armor fights where feelings and sentiments are more important than the fight itself.
Additionally, I never said that the side characters were good. Tama is good just because he's mentoring/a close companion of Sakuna, but the rest of the characters -- especially the human ones -- are extremely cliche. Kinta was supposed to be a reclusive, polemic yet perhaps misunderstood or kind character that could have been explored a lot more than it should have. His whole arc with Yui kind of makes sense, but it just seems quite rushed and there's not enough exploration into the character relations afterwards for me to care. In fact, after Kinta's and Yui's character arc, he kind of just becomes a completely different character, which is to say he becomes a nice and generic side character that never contributes to the plot again. Tauemon, Myrthe, and Kaimaru are also similar in that there are some surface level descriptions of all of them, none of which are going into depth, and they also similarly contribute literally nothing to the story other than sometimes functioning as a plot device to a Hero's Journey.
If all of the human characters were likeable, the slice of life farming with some fights and magical happenings could have carried the entire show for 12 episodes, but unfortunately that would require good writing capabilities. Instead, if you slap an already failing cast of side characters and shove them away to make way for a generic and below average shounen show about beating the big bad boss guy, it's still slop, but you can get away with the terrible writing you had in the initial half of the show.
Art was fine, probably above average definitely when it comes to character design, details, and renders, but it was quite obvious that 90% of the budget was focused on the first few episodes where the visuals were quite a few notches above the latter parts of the show.
Overall, an uninspired anime adaptation that could have been great if it focused on character development and better writing.
