I dont mind buying apps for my granddaughter. ANYTIME.... BUT... $5 for a 1 hr game is a bit steep. If you want parents to buy this you MUST have more levels. Dont get me wrong its an excellent app. It does exactly what it says. It teaches them reading,how their eyes need to be sharp and the problem-solving action is excellent . But so short and so expensive. Helps them learn. Its not about people getting rich but the next-generation being smart. Thank you for listening.
