Very good looking game, and it plays well! I really liked the sound effects when you hit the boss, it reminded me of Zelda Wind Walker.
It's way too hard in my opinion, being killed in one shot by the boss is too punishing. I only managed to get him to 50% hp, and I insisted a lot because the game plays that well.
The bow would might be better if you could aim while charging your shot, many times I dodged in time and was in a good spot, but not aiming in the exact right spot and lost a golden opportunity.
