iPad Mini 3 / 16 GB
Latest version of iOS
After playing an adventure for a while, I've noticed that sometimes the motion to swipe the dice becomes unresponsive, i.e. it may take 20 or so quick swipes in succession to get the dice to roll. Closing the app and re-launching doesn't appear to resolve this issue. It's almost as if just the dice UI freezes. Regular menu items and card access appear to work.
Consider adding a button to the UI to start the dice roll.
