I've recently purchased and played through half of the Vita version, and to anyone interest in it, don't get it. While framerate retains 30fps throughout most of each stage, there is significant framerate issues where it will lag at atleast two sections in each stage if not more. I've made it as far as stage nine where the game becomes unplayable as the game lags almost 100% of the time. In what might be a futile attempt, I've emailed Tecmo Koei and told them they owe me a refund and a prepaid box for return shipping to them.
