This app is really fun, my 2 year old Nephew loves it and caught on quickly how to use it. I only have 2 complaints. Being this is a learning app, I noticed some animals are incorrectly named (ex cheetah is labeled jaguar), and you did not include reptiles and amphibians. Second issue, after completing all 4 levels for the paid app, it led me to a 5th black screen with green leaves falling and locked areas I cannot figure out how to access (unless the app is still being updated). Overall great app I like it!
