Unlock all levels once purchased – Math Games for Kids & Toddler Review

You get Level 1 for free, but have to purchase the remaining four levels. Personally, this app shouldn't be more than .99. However, I clicked to unlock other levels and it didn't work for me. I like that it keeps track of the number of correct by providing a score (10pts per question and 10 questions per level). I also like that the narrator repeats the math fact after it was solved.
