It's a good, but also cliché, start to an "overworked and reincarnated and my new family mistreats me" isekai story. One thing I felt- after spending her childhood and adult life providing for her mother and younger sibling, they tell her, "I got a job so I can take care of the family now. Please focus on yourself." And that's very sweet, but... wouldn't working together as a family unit be even better? A moot point cause she is immediately hit by truck-kun.
There's some muddiness about when she can do unbelievable magic, and when the best she can do is steal and run away. A lot of unknowns because we haven't established what magic can do in this world. Maybe running was a terrible choice, or maybe she's an invincible God who lives in the forest like a queen. It feels like the theme is "back on my own world I suffered because I had to do everything myself, and now in the new world I will succeed by doing everything myself!" Which just reinforces her suffering in her old world.
