This game has a unique concept. Scaling the world as an interpretation of the theme was something that didn't cross my mind. This is an interesting take on it. Pretty good execution too. The Stealth sections that you added was a pretty good creative twist on this. I loved playing this, watching the ball bounce around and then get big enough to crush through everything was satisfying.
I wish it was longer, and you could have added in a few more enemies to make this more engaging and strategic. I really enjoyed the stealth part, but I feel like it ended a bit too fast. Since this was made in a game jam, I understand the time constraints, but I hope you build up on this.
