Mother Loose is a shortish retelling of several nursery rhymes in a parser format. You encounter Mary and her Lamb, Humpty Dumpty, etc.
The game isn't that long. I played around for a while, getting some points, and having fun, and then peeked at the walkthrough. It turned out that I was only one puzzle away from the end, so the game is pretty short.
It also seems that there are multiple ways of solving many of the puzzles. Some of the puzzles relied on knowledge of nursery rhymes. One puzzle's solution in the walkthrough I thought was unfair, but then I looked at the hints and realized that there is a more logical alternate solution.
Recommended for those looking for PG games.
