Very bad parry detection. – Infinity Blade Review

I spent 3 hours learning every single move of the final boss in the first run so that I could parry his moves and even when I pull off a flawless parry it tells me that I swiped in the wrong direction. How can a direct upwards swipe be anything except directly upwards? And The other third of the time it doesn't even register that I swiped.
