I remember playing this game some time ago and I returned to it recently. It's amazing that it is still one of the best games around. Splendid puzzles, good hidden object scenes but most of all an interesting story and consistent world that makes me return to Ravenhearst :) I recommend this game with all my heart.
I'm not a time management player (I prefer good old adventure games) but I played previous Fix-It-Up once and decided to give this part a try too. It sucked me in and I didn't even notice when I spent much more time then intended on selling and buying cars :) Excellent way to relax after a day of work. It is challenging but in a pleasant way. You just play along using your mind just enough to still relax.
