It didn't quite register what I was supposed to do, even after reading the game's instructions in the description. I think a message of some sort should be displayed at the start of the level, giving the player direction. I think that if the NPC characters and the environments were color coded (like red and blue), it would be easier for the player to glean that the NPCs belong in the same colored environment. I do think the concept could work with additional iteration. Good effort!
