The animations on the dice and the way they bounce out of each other looks great, which was why it was a bit disappointing to see so many default unity textures. In my personal taste, I don't really think a game should use default textures if they can avoid it, unless it's intentionally trying to break the fourth wall.
The gameplay itself was cool, and the way the room would fill up with dice was chaotic in a fun way. Overall, nice job!
