Press the green flag to initialize. Follow the prompts of the sprites to see different motion and animation.
The arcing sun motion was the biggest challenge. I followed some example script code that Google Gemini AI overview gave me when I searched "scratch move sprite in an arc". I can't find it again, but it basically guided me to use sine and cosine functions to define variables that work together when I change the x and y position in a loop. It took some tweaking but I got pretty much what I wanted.
