Very interesting game idea. The controls are easy and intuitive, but there's enough depth to incentivize exploration.
There are some bugs with the game crashing and progress not being saved. The crashes occurred while I was quickly clicking through the color menu.
The art is quite nice, I like how the clients respond to what you're doing and the pulsating glow animation on their portrait. The interface design is excellent and the menus are easy to use and understand.
The game gives you room to add extra commands that the client is neutral to. It might be fun to have some sort of alternate ending or bonus for sneaking in an extra set of subliminals.
