Well, I'm impressed! There's basically a whole game in this update alone. Visuals are nice, music (well, ditties) are nice, although voices are too quiet and controls aren't tight on mouse/keyboard. The actiony-nature of this chapter is... Different to what I expected, both from this game, and from a Sim Brothel spiritual-successor, but I sure am having fun! If anything, I'm a little sad that this will only be one chapter, because it won't become a game onto itself.
One thing I would defintily suggest, is not rushing players through the tutorial. The part where you start up the drone is basically the ONLY chance you get to figure out half of the room names. Or, if you really don't want to encourage the player to look around, you could put the room names inside of the rooms. Otherwise, the player will basically just wind up cleaning every room at the same time, because there's no consequences if you "clean" a room that's in use.
Having phone guy explain everything a day too late is... An interesting choice. I'm not sure if this is for realism's sake, or if you want to give players the chance to figure things out on their own, but it's a brave choice. Is it a successful choice? Ask someone else.
Seems like other commentors have touched on the drone. The only bug I've had so far is when it falls through the staircases, though it's definitely too slow on later levels. A quick-fix could be just to put all power boxes on the first floor.
Online scoreboard when? :D
