Got to 5 stars with 44 Floors, literally half of my building was Large elevators. Hired about 40 maids as well, they are cheap and dirtiness is a common complaint. Every time a complaint comes in about a service, build another one. Don't be scared of the odd loan, but don't go overboard. Keep an eye on the comments section and the graph section, both are invaluable. This got me 5 starts in no time :)
Good game, addictive enough to make me want to finish the quests but all the stuff on string following you got in the way sometimes, if the keys and quest items could be in your inventory without being seen that would be good, and maybe instead of the little guns following you, your main gun would just get better and multiple barrels. Great game though, music is especially catchy :)
Obscenely hard. How can you expect people to find these tiny holes etc. Most people will get annoyed and click to the walkthrough. There is some logic required but mostly its just hunting fot tiny things you don't know you are hunting for. 2/5
