Yo, played your game for some time, noticed a pattern: there are 2-3 dice numbers falling, first time they were 3 and 6, second time they were 2 and 5, the third they were 1 and 2. And what's interesting about the third time -- the dice was 1 and the falling ones that were 1 as well damaged me, the 2's gave me points tho. Overall, nice idea but i think some refactoring of randomness for spawning dice and fixing the initial one value will be cool. The sound of picking up cubes could use some variety, like random pitch or different sound effect. I also liked tha music that you picked there.
