I was going to say that the sentries would give her a hard time, but I didn't know you could get rid of them in the options. You should be aware that you are constantly having to gather resources and that crafting all the things you need can be a bit complex. I'm assuming you can't get rid of fuel needs in the options, and everything in the game requires fuel of some type, including all of your tools, most of which need different fuels.
The Waypoint update of October 2022 added a Custom difficulty, in which you can turn off all fuel costs, double the yield when mining resources and make crafting and all items available in shops completely free. With all of that I suspect the amount of resources you need to gather will be doable for her, or I'll be able to do it quickly myself if she wants to craft something specific. If that's still too complex, she can also try playing in creative mode.
She's old enough to enjoy Wizard101 now, and the first world is free if you ever want to try that. My kids played that from age 5, and they still play it occasionally today. Combat after the first 3 worlds gets slightly challenging, but the first three worlds will last you a good while, and you could always help her with strategies later. Game is very well written and every line is voice acted. Wonderful game for kids.
I'll definitely check that out, thanks for the suggestion! Every line being voice acted is amazing, as helping her read dialogue is quite a bother for a lot of games. Especially since she wants me to translate it all, even though she understands English pretty well.
