Very cute game! I loved the subtle humor used in describing grown-up versions of nursery rhyme characters, including the easter eggs such as with Peter. The game feels easy to figure out and play and the writing is engaging and informative.
It took me 601 moves to rescue Mother Goose. I got a bit stuck with waking up Willy (didn't search enough and was trying screaming and shouting) and making the children shoo (was trying to dance and play with them). Also wasted a number of turns on typos/invalid commands (eg ex instead of x, coming from MUDs) and blank command entries (again, a MUD holdover where text isn't deleted at entry).
Overall, I found it very charming!
