Final Project Idea

I want to make a game like "Alight" by Sphaeri ( https://sphaericactus.itch.io/alight ), but change it to be dance related. I want the character to be a ballerina, that maybe is spinning, and she is avoiding certain things (like tomatoes etc). But I only want the score to increase if she collects something specific and I maybe would like to add different difficulties.
