I think doing a dotted line similar to the visualization technique for the path that Bibi intends to walk will be a good solution for that. Good suggestion!
Each rank of employee will have an animation tied to them. So in the full game, any time you see someone in a unique set of clothing, they'll have a new animation. For clarity I might also slightly fade employees who have had their animations collected already.
The futa tag is for one of the new employees in the late game. She'll be an optional boss. Can't say too much about that one yet!
