Very neat; I see where you intend more with plenty of room for VIP guests, expansion upstairs and a bar, and look forward to it if you do.
Gameplay, I'd like to see more systems of consequence or goals and purchases for completion. Perhaps a quota you have to meet with the boss every few minutes, or maybe interest raises steadily when unpaid. Less consequential goals like the option to spend money to change the appearance of the brothel would also be cool.
So far what you have for visuals is good! Good animations, character design, and I enjoy the dynamic lighting! It would be a treat to see more characters, from clients to more hired help, or a bartender or DJ. Moreover, if you played with the colored lighting more, such as the option to turn on strobe or party lights for the VIP lounge.
Sound wise, all the sound effects are good. The lack of any kind of music does sadden me a little, but the choice of SFX and usage was all good in my books.
I had to stop before I paid back the boss, because all my helpers softlocked into a lewd animation with no one, and that made it harder to make money as their was only one stall I could attend to.
