Finished with 45 girls (after reading the comments here for hints). It confused me that some of the signs say what to do (like stand on the button for 10 seconds), but others say what not to do (like "don't block the way"). The cat puzzle was also pretty unintuitive without the sign, I don't know why blocking the way would cause it to break out for the yarn. I liked the art and the randomly generated characters were fun.
