Art is amazing.
Played through and beat all three levels. I made it through level 1 and 2, then had to go back to the tutorial and learn about what the damage type symbols meant in order to pass the third level. (For the third level, also key was building up a large counter-attack stat.) Really enjoyed the witty tutorial explanations.
Mimi turning into a sword in the intro sequence was really cool to see. Would have liked to see more of that. Maybe with her turning into the weapons that you end up playing as an attack animation, or as artwork on the weapons cards themselves.
Also played wearing headphones. The beats switching sides definitely helped bring an extra level to the music. Great game!
