Interesting concept and an intriguing puzzle game. It wasn't clear in the beginning (and still a bit now) what the icons mean and what they like and don't like, so I would recommend having a popup when you hover over each icon. Also I would recommend having a larger diversity in characters, as most have the same skin-tone and eye-color and I ran into the same ones multiple times. I would recommend splitting them up into different chunks to make it easier (and random tip, outlines make everything look better). Overall quality game and quality idea.
