Under rating threshold (hideshow)
Just before the part where the logical matching game is presented, Julia's and her aunt's text are merely the same. Then in the matching game itself, the tiles flip back too quickly after choosing the second card so that you barely see what is even on the second card. It should have a sufficient pause before it does that.

Ok, so far these are what I see that needs work. The tutorial balloon can't display some text sometimes when it is too long. It would also be helpful sometimes if it changed positions so as not to block whatever it is talking about. It would also be helpful to have some sort of description for what each building and upgrade is. Then some way to see the overall statistics that we have so far. I'll see if I can give some more suggestions after I progress some more. :)
