Seems like I already keep coming back to this one. The better you do, the better your flock of ducks, which is appealing even while it (by design) makes your duck harder to control. It took me several rounds to begin to understand what the bread (?) does, and I'm still not sure I'm all the way there—you can still add an explanation to the page itself if you want, I believe. Good work, and thanks for putting it up!
