love the cinematic animated comic style story. (its a pretty cool way to do a tutorial.) though game play could be improved.
attacks could be telegraphed better. ( have a small animation that plays before the swords move, that way you know what sword is about to move and making it easier to escape its path )
usually you would want to keep all attacks of a certain type the same, so to me the attack with the shock-wave feels a bit out of place. personally i would replace it with a stomp animation for the enemy. (make it big and telegraphed so its easy to read and avoid)
since attacks would be easier to dodge you can decrease the amount of health the player has (which will make attacks feel like they actually hurt, combined with shaders and/or animations to emphasise the impacts of hits will improve the feel of combat).
