Ok. Thanks for the feedback!
I tried to proofread everything, but, well, oops. And thanks for mentioning the red peg not being in the instructions. As you know, it's easy to forget to mention everything when trying to explain something you know just absolutely front to back. I'll see about fixing that, too.
I prefer the drag-n-drop of the disks, which is one thing I though could be improved on your version. I'll have to see if I can add click-to-move to my version. I made this in only a week, so it shouldn't be too hard to add a simple feature like that. (Famous last words....)
