Super cute! +1 to playing as a cat. And this is a lot for a first game-- good work!
It took me a long time to figure out that I could use B to throw a weapon because I was coming from the jam page and it didn't show me the controls you wrote on the game's full page. It may help to have text floating near the first spawn that tells the player controls (though, with multiple control schemes, adding code to check which they're using is a lot-- so this is kinda a "cool thought" and not a requirement).
Additionally, I found a point in the jumping on clouds where I could fall and ended up falling infinitely through a gray background-- these might be areas to try to playtest for when possible. With just two days to work, it's a sort of expected oversight.
All of the art was adorable, and I'm especially glad that when I idle long enough the cat turns to the camera-- great choices there! The UI for your health and yarn-bombs remaining were also very clear and easy to understand.
