In general, I feel that the game is well-paced, interesting, cute, and fun. However, I wish there were a way to tell when the day was ending, though it isn't hard to tell because all the customers clear out. My main complaint, actually, is that the types of customers become too many too quickly, and it's also a burden trying to accommodate all of them. Perhaps one should be able to get more floors more quickly.
However, the rest is GREAT! I spent an hour playing this, and it was very fun. Keep up the good work!
