I'm a game programmer and I figured this level out after analyzing the code hint. Shame you're replacing it, I think it could work with a better hint. The hint is legible to a programmer, but it doesn't read like a "sentence" as well as some of the other hints.
I'll admit it was annoying how much you have to rotate the camera, a mouse sensitivity setting would help with that part.
I really like the way you get the bug in this level, by scaling up the duck to move a block. Are you planning to preserve the concept of scaling the duck up and down? Perhaps use a different method to scale the duck?
