Yeah, you hit the bug that I’ve been dying to upload a fix for. It’s exactly as you thought, the game is tracking the scores of the other brain colors if you started a game with less than 4 players. Pretty big oversight on my part...
It has since been fixed though, and the unused colors of food have also been updated to only reflect the colors of the brains in play. Unfortunately though I can’t upload those fixes until the voting period ends.
Still thanks for playing, and thanks for the feedback!
