Here's an honest review from a long time player. The artwork is fantastic, but there's just one problem.. This app has MAJOR issues! It constantly crashes or lags despite clearing cache & turning on "smoother running" settings. You can't easily force quit out of it. Animations are sluggish. It takes up a LOT of space on a phone (300mb-1GB), and the size balloons if you don't track it. You have to uninstall & reinstall to get the size down each time. The app needs MAJOR fixes to run better.
