I have no Ruby skills at all, so I am probably within the "target group". One suggestion I would have is: It would be cool if there were some kind of putting-it-all-together-yourself thing at the end of each level.

This would most likely mean going back to look up certain functions from the challenge, but prep one more for later when actually doing some coding on my own.
