Very cute and wholesome :D The music is lovely and I absolutely adore what you did with the background on the game's page. The art is sweet and the gameplay loop is easy to understand. The prerequisite isn't really clearly present to me, but the concept is nice!
I'd love to see more audio and visual feedback, for example when getting hit, or when you nearly miss an object having some whoosh sound play. The animations are sweet and the water animation is really pretty to me, love the vibes!
Overall I'd say this is a very solid and heartwarming game, thanks for letting us play!
