Game is good and worth the cost, but it's not so fun to play as expected.
PRO:
-very nice art style
-combat simple to understand (just 4 buttons: attack, parry, dodge and interrupt enemy's attack) but challenging to play.
-satisfying parry and attacks
-nice concept of combat based on stamina. It makes the combat more clean and prudent
-short and interesting story mode
-duel mode vs another player or vs ai

♥♥♥♥:
-combat a little bit slow, maybe beacause of input lag or slow/not fluid animations
-performing an action doesn't override the previous action. For example you can't parry until the animation of the dodge is finished. This makes combat slower and less satisfying.
-I can't really understand the parry concept. Parry restores you energy but it doesn't let you counter-attack nor even reduces enemy's stamina. Parrying against nothing, attacking and dodging drain your stamina and when you run out of it you can't stop the next attack, resulting in a death. But you can't drain enemy stamina: ai enemy usually attacks you when you are in range and if you correct parry all his attack you keep restoring your stamina while the enemy loses it; but when the enemy remain with his last stamina slots he stops attacking, recovering the stamina...and the cycle restarts. So you can't kill enemies draining their energy by parrying attacks. You have just to wait until they fail an attack and hit them just the moment after. Or you can dodge behind them at the right moment. I think it would be more satisfying if a sequence of correct parries (that are very satisfying to perform) could give you the occasion to hit the enemy.
