I love the concept, but the minigames are kinda borked. The maze starts out trivially easy, almost impossible to lose, until she abruptly decides to stop messing around and it becomes completely impossible to win. The concentration game always gives you a random chance of sweeping the board in your first move, but when her turn comes she either chooses in a completely random, brain dead manner, or she magically knows where every single card is and just gets to declare herself the winner.
If she kept track of every card which had been revealed and always made optimal plays, that would still be better than any human but would give you a fair chance. Instead she just openly cheats, unless she wants to let you win.
