Alright, I was able to play it now on desktop. I love the art, especially the boss and the main character. Game feels juicy, thoughtful, good pacing, and thoroughly enjoyable. I liked the story element too, it frames the game's content well.
My one constructive piece of feedback was that the collisions felt a bit off. Not sure if it was a timing thing or whether they were offset from the sprites. (this did not affect my rating, just a constructive tidbit)
