This entry both has a really cool concept and a beautiful execution!
Like a lot of commenters, I am unsure of how the game counts the number of dice to throw.
I though that it started with 3, then removed one if the armor attacked matched the armor defended, and another one if the elements matched, but it sometimes throws 0, and sometimes 3 when I'm defending the exact same things the opponent is attacking, so I'm confused. But still, I like the gameplay and the idea.
Visually, nothing to say, the sprites are wonderful, the animations are great, and the music goes well with the theme of the game. The only thing that stuck out a little was the armor's design, but apart from that it's perfect!
Really great submission, excellent work to the team! =D
