An amazingly impressive project to make this quickly! There is a ridiculous variety of characters that are all gorgeously modelled and animated! Environments are just as varied, and visually appealing. There's popups and particles to show what's happening. The whole game has a friendly, warm and colorful look to it and loads surprisingly quickly in the web version in spite of all the graphics!
The gameplay core is solidly built with good UI design and controls. The excellent pathfinding allows players to set up shop however they desire. An option to lock new objects to the grid and rotate 45 degrees at a time may be a good addition for players who like precision. A strong gameplay hook would give players something to aim for beyond maxing reputation, building every type of item or hiring all the staff. Maybe the staff can have some days off to enjoy the club?
The world's narrative is mostly told in the form of application letters, bills and the tutorial at the moment. There's some creative writing in all of those things, but it doesn't fully feel like you're getting to know the characters just yet.
Audio work is good with an excellent soundtrack, a wide variety of sex noises and effect sounds for every action you do. The music didn't always play for me and the the sexual sounds are a little too frequent, so some tuning may be needed for full immersion.
This is a difficult game to make in a year, and you've built it in month! Not only did you hit the basic goals of having a client, a worker and an object, you've made a wide ranging variety of all of them! I really admire your dedication!
