This is great! I think the parry controls could be a bit tighter and more forgiving (or maybe just the attacks better telegraphed) but overall I really enjoy the concept of requiring the player to parry. It might be interesting to break up the parry-attack-parry-attack cycle a bit by also refunding the strike if you kill multiple enemies at once, or by being able to store up attacks when deflecting arrows.
I think with a bit more polish, this could be a really addictive arcade-y game. Nice work! :)
