Great app, but could be improved – Book Towers - Brain Teaser Math & Logic Tower Puzzle Review

I like this app, but I could easily love it with a few minor improvements. It is very addictive! Please add some way to keep track of your lowest number of moves for a level so you could know if you've improved! I would also appreciate a hint button. If I'm stuck, it would be nice to get one hint rather than the entire solution. With those changes I'd definitely give it 5 stars because it is a fun game!! My preschoolers like it yet the harder levels are challenging for me! Great for all ages.
