Very cute. I liked that you added extra animations, for dancing, running, balancing on edge. The character feels lively.
I completed it, although it felt a bit too hardcore for me. Maybe it's the lack of control while in air or the speed of drilling is too high. I understand this could be intentional and the palyer can get used to it, but maybe this would make the game less frustrating at times.
Overall - very polished game. The core mechanics, leveldesign art, music - everything works perfectly together. Good job.
I was not expecting that ending. I thought at first, "Oh, a boss fight?" 😅
