This game is all about the laundry machine. Keep that thing running nonstop and you get the fastest possible times. Clean up other things while the machine is busy and postpone cleaning up repeating messes until the end. That's all the strategy there is. Incidentally, that means some "perfect time" targets are impossible to achieve because you cannot speed up the laundry cycle.
It's funny looking, but low-res and the (first) nanny appears the be cross-eyes in the art. The stereotypical mess the family makes is fun to see, but overall this game get boring real fast. I guess playing the demo for five minutes shows all gameplay it offers: it's a threadmill.
