Simple and clean. I liked the overall presentation and the quick building of tension when the dice start coming at you. Could benefit from the addition of a secondary goal or ability (shooting the dice to push them back for example). Not too shabby.
I originally wanted to add them but as I put the falling dices together it felt like adding a gun to shoot them down might destroy the tension of the game, so I just added slow-motion too help player out, press the space button to activate slow-motion by the way!
