I like the minimalism in terms of both color palette and the things you chose to include to depict the story. I think the plot is quite cohesive, and I appreciate that some things are left for the player to fill in. In my interpretation, the character is hunting down royalties to extract their essence (anything in yellow) and rip them of their status (causing them to become red/inferior). The witness at the end, of course, had to be taken care of.
