I really like how intuitive it is to play, and how natural it feels to adapt to a client's needs. The aesthetic is very harmonious: the pixel art portraits, the bright colors, the simple sound effects, and the point-and-click interface, all felt like they belonged together. I also learned about some new kinks!
Edit: I do want to note though that the font is hard to read at this low resolution ("What is a 'Bood boy'? Oh, right.")
