I love the art and aesthetic of your game! An office intern getting tested by his coworkers is a cute way to progressively add challenges. I thought each new challenge was unique too and generally scaled in difficulty. I also think that trying to balance and spin the ball was quite fun and a very creative take on the jam theme.
I have two pieces of feedback, I feel like the ball spinning was a little glitchy and sometimes the ball would teleport across the screen. It was also visually hard to tell when a ball was spinning so it was nice that you added the text that said "+spin". My other piece of feedback is I think it's worth considering if you want the user to need to press left click to spin the ball. There was never a case in which I didn't want to hold down the button, so it was annoying to have to keep it held down. I am also playing on a trackpad though, so you can take that with a grain of salt.
Overall an awesome game and submission!
