The theme for the jam was "Make Me Laugh", and as we found ourselves with two musicians in our group, we decided that we should obviously make a funny music game. After some discussion we landed on an homage to Epic Sax Guy (the saxophone later turned into a trumpet) mixed with some cat memes.
My main contributions were the mechanics of spawning notes, making them fall down, handling player input and whether that input happened with the correct timing to hit the notes or not, as well as points for hitting notes and health that goes down for missing them. Some more minor contributions were the menu, particles, and cats sliding in at the correct timings.
