The visuals are amazing! With the help of the instructions you wrote, I was able to understand how the game works pretty quickly. 🦆
My main advice would be to maybe use a different font for the numbers, since 2, 5, and 8 look very similar with the current one. A couple of times I wasn't sure which number the game was asking me to raise the temperature to.
I would also suggest adding a bit more feedback to the objects you can interact with, like making the sprite slightly bigger or highlighting it when you hover over it. I think that would make it much easier to tell what can actually be interacted with.
But overall, great job! Huge props for the art especially, it looks amazing!
