我应该如何在pygame中存储有关房间的信息？

rooms = {
    "room1": {
        "name": "Living Room",
        "description": "A cozy living room with a fireplace.",
        "items": ["sofa", "coffee table", "television"],
        "exits": {"north": "room2", "east": "room3"}
    },
    "room2": {
        "name": "Bedroom",
        "description": "A comfortable bedroom with a queen-sized bed.",
        "items": ["bed", "dresser", "lamp"],
        "exits": {"south": "room1"}
    },
    "room3": {
        "name": "Kitchen",
        "description": "A modern kitchen with stainless steel appliances.",
        "items": ["fridge", "oven", "sink"],
        "exits": {"west": "room1"}
    }
}

class Room:
    def __init__(self, name, description, items, exits):
        self.name = name
        self.description = description
        self.items = items
        self.exits = exits

room1 = Room("Living Room", "A cozy living room with a fireplace.", ["sofa", "coffee table", "television"], {"north": "room2", "east": "room3"})
room2 = Room("Bedroom", "A comfortable bedroom with a queen-sized bed.", ["bed", "dresser", "lamp"], {"south": "room1"})
room3 = Room("Kitchen", "A modern kitchen with stainless steel appliances.", ["fridge", "oven", "sink"], {"west": "room1"})
