Comme promis, je passe ! ;)
(Writing in English so that more people here understand.)

Semi-on-the-fly remarks:

1. It looks like the second page of the tutorial is not showing! (Or at least, there is one void display after the first click.)  Maybe there is important information there, which would explain why I did not understand several things at first.
2. In the tutorial: little misspelling: "it's score" -> "its score".
3. It may be me, but I have trouble understanding how things works, especially how challenges are resolved. For example, how do the different characteristics (= little drawings) work? Then again, I am not a tried card game player.
4. Going back to the rules, the Score indicator is still superimposed.
5. Aaaah, you have to hold clicking on the Score indicator too! I think this was not made clear in the rules, I was wondering if I was stuck!
6. As others have said, the drawings are really nice; both varied and with a sense of humour.
7. Finally understood that you have to SELECT a characteristic to be able to increase it (by burning the die)! I think this was not said in the tutorial either, but once again, I really wonder if page 2 is not missing… :s
8. Actually, the only thing I still have to understand properly is how the enemy/challenge’s score is computed, and how mine is. (So that I get how a challenge is resolved.) I am not sure how the full and half characteristics are counted; do you compute (full characteristic + half characteristic / 2)?
9. I managed to win! :) Although my understanding of how scores is computed is only semi-intuitive.

I think the game would be greatly enhanced by some more explanations or even a tutorial battle; but there may be a missing page 2, which would explain why I had a hard time understanding several important details. Some sounds would give it more life, too! :)

About the concept: I like that you connected randomness to strategy.

Impressive concept! The art is really nice. Good job!

Rolling, rolling, rolling... C'mon! Nice :)

The game is quite interesting, and the best feature is Art, which is nice and unique

nice :) 

Nice game! Impressive art! Well done!
