Fun and challenging. It took me several tries to complete it, but finishing it was rewarding. I liked the design of the castle and the gameplay of the stage. Great work!
I would say that Mr. Magni loves to include elements of playfulness into his levels. I like the balance, not the ball balance, but the balance between logic and playfulness on his set of levels.
My first ten tries or so were terrible and I felt that the level was impossible. My next try managed to get the ball into the green area at least. Two tries later I had it.
