It definitely looks like a fun game idea is here. Overall, I did have some issues with it though: My biggest issue was that it seemed to not really fit the theme, but rather the theme was just tagged on in a "see? there a die technically! and the name says so!" kinda way, which is a major let-down to me. Also, the time in-between the player shooting feels a bit too long, which wasn't the most pleasant experience to me.
That aside, the movement was pleasant, and the gameplay was nice.
