The mechanics are very cool! I'm still in the tutorial, with green and red.
What I don't like so far: there's always only one solution, so it doesn't feel like I'm playing. I want to learn it the hard way and die from my stupidity!
I'm at a point where the tutorial seems broken: the game asks me to do a perfect break, but accepted a solution where I was taking damages, because I used the unique red attack bonus on the previous turn (without the game prompting me to do so, just me clicking stuff), and thus the enemy has 2HP less than it's supposed to have... I don't want to use that +2ATK but I'm forced to!
