Get the people moving operating an elevator
Manipulate an elevator to get all the passengers to their hotel suites on time. Get the highest scores to upgrade your elevator cab and then your house. It's a rough day at the hotel, so we need to get the passengers to their levels fast.
Steampunk setting, various upgrade options - from elevator to the crowd, different locations (houses, mansions, steampunk-era hotels) would get you hooked.
