Honestly I just created only 1 pair to play the game, confident that if I was good enough I could succeed, little did I knew the game punish you for doing that, and eventually any character could turn immortal, not my proudest 2 runs.
I guess the concept is ok, but it should be pointed that you can create those pairs ingame, not on the pause screen, and if so, at least hint the players into doing that.
However battles are quite fun, except for seija, really hate her and those half inverted controls, many place to experiment and enjoy multiple spell card battles, the lack of sound is an issue, is not that epic and it takes a bit of the fun away.
Animations do their work but I would like there could be a way to teleport myself to the center of the screen when a battle is over, because its a pain in the ass to walk all the way to the top over and over again.
