Interesting concept, but the dice moves a little bit to fast making it quite floaty and hard to control. Also with the lose screen I noticed that when the game is full screen the UI shifts to the top left of the screen. Good game but needs some work.
Recommendations for the future:
- Slow down the dice movement speed
- On the first level don't have the dice start rolling off the book till the player makes at least one input
- Have your UI scale with the players screen size
