My goodness what a charming, polished, and fun little demo. The aesthetics are very cute, definitely giving "Aperture Labs" energy. The bright coloring is a great indicator of what's interactable, and nothing looks out of place. I love the music/sounds, they're all so sweet and cute. Controlling the character felt comfortable and intuitive, as did scaling things up and down. And god am I a sucker for making UI elements interactable and part of the game, that was such a delightful surprise. Really great job. I'm amazed at how polished the levels you have look and feel, I would've really enjoyed playing more!
