Won't let my play – Happy Park™ - Best Theme Park Game for Facebook and Twitter Review

I have an iPhone 6s. At the beginning when you have to click on the Ferris wheel the whole thing freezes. It won't let me click on anything. Other reviews also say the same thing. Please fix! Would love to actually play the game:)
