An easy 5 stars on creativity, a really unique game yet utterly dedicated to the theme.
Sadly I encountered a couple of bugs that sort of made the game unplayable:
Firstly, the enemy would reuse its dice to completely deck out its stats. By turn three it would have every box full. I restarted the game several times and this happened on almost every turn.
Secondly, after a turn or two I would stop receiving new dice on my turn. Sometimes I could click around madly and they would suddenly spawn and roll, but this was rare.
These bugs made me really sad as I love your game concept and really wanted to play it. The concept of growing your character per-battle, watching that skill tree fill up, that's really good and sounds uber satisfying. And being able to hold your low rolls to activate the special moves is really clever too, it means the player is never totally screwed by rolling low and they don't really get that pang of being screwed by bad luck.
Reading other comments makes it seem most people were able to play just fine so I'm not sure why I wasn't able too. I would love for you to continue development because the concept is so solid and I'd like to play a working version haha.
