I really like the black and white artstyle, it's very cute and charming with good shape language, the contrast between the two shades is one of my favorite things to do in art :). The music is catchy and it really gives it a chill vibe.
Gameplay feels very nice, it's fun to parkour around and over the bosses while fighting.
(spoiler warning)
A few things were not clear to me at first, like the disappearances of items once you get a new one which I understood after some time. Near the end I missed a cloud and the meteor event would not play, so I had to go back and hit the cloud I missed near the flag, after which the meteor event worked.
Overall it was fun and entertaining, very good work!
