You have a README which is great (fill this out however), and you'll need a License file as well (these are two main criteria for open source category).
I love the narrative you built, super fun and cute. The music and sound effects are great too. Maybe make it a little easier to start out; not all streamers can hit the ground running with just a bowl of Ramen 😅. I was actually playing this one live on stream so it was very topical.
