I have a fondness for simple dice games, and this fits the bill. It was easy to pick up and play, and felt rewarding to play both slow and careful and fast and risky. The dice look good and the rolling animation was well done.
The lack of sound is the biggest drawback, in my opinion. I really wanted to hear the sound of the dice rolling, and I think some background music would also be nice.
I would also love if you had a score tracker, where you could see past games and compare your scores.
The one other thing I might add would be a little more details in the rules. It took me a bit to realize that a die being held didn't get counted for combos in the next roll, so I was a little confused as to why sometimes having something like three 1s gave me more score than other times.
I had fun playing this and could see pulling it out again if I wanted something short and simple to spend a little time on.
