Upon arriving at Pi'illo Castle, your first task is to explore the immediate vicinity. Follow Starlow's instructions to move Mario and Luigi around. You'll encounter your first few NPCs and learn how to interact with them using the 'A' button for Mario. The game will guide you to a room where you find the first Pi'illo. This is a critical moment, as it introduces the central mechanic of the game: Luigi's ability to sleep on Pi'illos and open portals to the Dream World. After Luigi falls asleep, you'll enter the Dream World for the first time. This initial Dream World segment is heavily tutorialized, teaching you how to use Luiginary Works to progress. Don't rush through it; understanding these mechanics is vital for the rest of the game. You'll learn about Luiginary Stack and how to use the touch screen to manipulate Luigi's dreams.
