One of the more impactful rooms you can unlock during your Blue Prince run is the Laboratory. Blue Prince has been praised by critics for its tantalizing approach to gameplay. Centered on the young man Simon, who inherits a mysterious mansion from his late grandfather, the game challenges players to find the mythical 46th room in this 45-room house. You can plan the house’s layout yourself each day, drafting one room at a time. The catch is, you can only take so many steps before getting tired, and every night, the entire house resets itself.
