3.0
Basically, this is just another mindless clickfight game where you hit attack buttons when the cooldown ends and maneuver yourself away from red zones where enemies are about to attack. There are dozens upon dozens of games on the app store that do the same thing. The only reasons this game managed three stars are the lack of annoying spam, and decent responsiveness for the controls. If you don't read Japanese and you're not a Samurai Shodown/Spirits superfan, pass on this.
Even though I'm a fan, I gave up after a few days.
