The art was amazing! I love the creature designs, it almost feels like you have some lore about this world that would be really cool to know. Or keep it hidden, like a Miyazaki film.
I liked the mechanic of the arrow and how it has that weird curve, forcing me to lead my shots.
The music was so good too, I played in Chrome, but I´m going to play it again in Firefox just to hear the music better (stupid annoying audio bug).
As others has said, it is a bit repetitive, I would have liked to have different levels, maybe the ashes are scattered in other places.
Really good job!
