not sure if someone suggested, do you plan on having idle helpers be active in other crops?, i mean my carrot farmer is to young to retire, i would like them to help with corn or pumpkins.
decent game, but your puzzles make no sense, you should put clues in the room, no one wants to guess witch random buttons should be lit, and no one wants to use qr codes to play a game.
But there are clues. Pay more attention to the floor (remember control hints). Puzzle hints are always located on the same floor where puzzle is. QR codes are meant to be used only if you need a solution.
