It’s not coop, but I recently played “The Big Con” (with Gamepass) and it’s more of a fun ride with an easy control scheme and decent puzzles. While the FeMC isn’t the classic “strong female lead”, she is a teenager growing up and develops throughout the game and it’s story.
I found it very funny (your daughter might not get every joke, tough), depicts some good topics (trust, family and responsibility) in a very lighthearted way with a cute art style. :)
