Cute concept and story, with nice art to match :)
Vertical platformers aren't too common so it was a nice change to see one, along with responsive jumping mechanics and physics (the mushroom bounces were very satisfying haha). As others have mentioned the sound was very quiet, even turning my speakers up all the way I couldn't hear much unfortunately, but it's a minor issue in the grand scheme of things. A well made entry for the jam, nice work :)
