I got my Tokyo mall making a profit, then wandered off and cooked dinner for the family. By the time I got back, I had over $2 million. Finishing the level should be easy now... lol
Solved all puzzles without cheating or using walkthrough. Now I feel smart. Yay.
Then I went back and found all the gems. Took me ages to find the last one. Drove me nuts. But then I got a message saying I'm awesome! Woo, a game validated me.
Time to do dishes.
