I like what you did !
Classic management/tycoon game, Only downside: it's way too easy though, difficulty is the cherry on top of those games in my opinion (or chosing your difficulty/settings).
Really love the fact that the clients don't know what they want, that you have to look for their needs, get to know them better and get rewarded for doing so, etc.. that's a real plus and what keeps the whole thing engaging.
