Very interesting idea to make the attack a potential danger.
But i was still missing a little more player feedback, it would be very important for example, to show how much life the player has left. With that, the player can weigh up wheter he prefers to withdraw or to attack. In the beginning i even thought that the arrows were a second attack to defeat enemies.
It's interesting that the player is very slow, so you force him to use the dash as often as possible. Dodging the arrows is still very difficult in my opinion.
I love the overall presentation of your game. Lots of detail is put into the pixel art.
All in all i think this is a pretty solid submission. Good work.
