I'd say it's a pretty casual game, mostly walking around, interacting with NPCs, doing some puzzles. You jump around, but I believe it's all at set places, so you don't really worry about platforming fails. But it does have some points where you're chased by enemies and have to run away, and
some people had some
difficulty with that. If you're sitting down and playing together, you might want to watch some videos on the Zurk encounters beforehand so you know what's up, or maybe have her pass off the controller for those bits if they're too much.
