I love the art style and aesthetic of this game! And oh my goodness, the voice acting! This a beautiful implementation of the theme, and I would really enjoy playing a visual story like this.
My main issue with the gameplay is the limited arrows. In my first run through the game, I ran out of arrows on the 1st stage and had no way to fight the dogs, so I had to restart. Having some way to grind normal arrows would be appreciated, so the player can continue going even if they accidentally spammed arrows early on.
I liked how the main character could change to bird form to travel across lava and scout out the map before engaging in any combat. I used the bird form to avoid fights and gather all the skulls I needed to unlock the last area without using my precious arrows, which added some semi-stealth aspect to the game.
The poison arrows felt like the most powerful arrows, since you could shoot and bait all the enemies to kill themselves in the poison cloud. The other arrow effects were interesting, but ultimately I used them interchangeably when I ran out of poison arrows.
Overall, I enjoyed the experience of playing! Great work!
