Great content, but bugged

I love this game, but it doesnt work fluently.
Iphone 6 with IOS 9: the layout is too small for the screen (my status bar comes down for 1,5-2 cm) and the game gets stuck whenever i put an element on the "?" Or "i" symbol. Have to close the gme and restart. Thats a bit annoying. Otherwise its great.
