The dice booty got me LOL. Thought this was a really cool idea. It was challenging too. Gotta be honest, didn't get more than a bronze each level.
Some minor improvements: It was a bit difficult to see the dice around or behind the player at times because of the 3D aspect. Maybe having the dice number hover above when you put your mouse over it would be helpful for this. Also, the noise he made when you rotated the dice was pretty awful haha, all the other sfx sounded great, but something about that noise just made me cringe.
Overall, really good job with this! It's super polished and I love that fact you have not only six levels but there's good variance between each one to keep it fresh. Great game!
