I love the narrative you came up with for this!
The music you've written is very cute but not at all lacking in depth and contains a nice contrast of emotions without losing that light-hearted feel and also feels like a coherent soundtrack whilst also feeling perfect for the game you described.
Some great melodies, motifs and some very nice use of extended percussion and choices of instruments.
Well done for putting together a video to accompany it that was a nice addition. The artwork is simple but fits the game you've described and the mood perfectly.
