This is incredible on every level and matches the theme so well. I love the types of balls and the different attributes they have, it's amazing. I think it would have been cool to have a ball that does health and damage at the same time.
I also think the board could have been altered throughout the game somehow, either by swapping out with different boards or changing things with your ball as you play. Overall this is one of my favorites and the concept and design is flawless. So creative!!
