This is one of my favourite games.
I decided to leave a feedback because the people leaving bad feedback cannot be intelligent. First, if you bought a category on any devices and want that category on another device, just look for the restore purchases button and you’ll unlock what you already own. So that solves the negative feedback from most of you. But those that are looking for something educational fun and mind bending. This is it. I think it is fairly priced and the maker of the app wonderfully designed the app. I ask him to please not alter this app and create a topple 2 with new puzzles. This is what kids should be playing instead of the mindless games out there. Thank you developer. You deserve this review.
