(7-year-old's review, typed by her dad)

Well at first it was easy, and then that like ninja thing where they say "try to dodge this and you'll get some more things", like there's ninja stars and it's so hard, and the ninja stars stick to the building, and it's hard to build it, cuz you can't like extend, like make it bigger, like your attachment. So you can pick it up so easily. 2 stars for the easy bit and 1 and a half for the ninja bit. And I haven't gotten past it!
