Every color would be a diffrent attack, red sword is a well balanced, pink axe is slow but strong, orange arrow/spear is fast but weak. Dark blue gets you a block, with stacks up for you to use when you see an attack, green regenerates 1 health, cyan fills up the ex/dx meter, and yellow and purple blocks activate it. If meter isn't full, they change into sword and axe respectivly. You have to line up 3 or more to activate all of them, witch you do by rotating rows left to right. As for the story i have something in mind, but it's not 100% there. BTW I saw someone else doing this and wanted to give it a try, but not to rip it off. Hope y'all like it.
