This seems like a lot of code (at least for a beginner like me), but it uses loops and lists so that the user can navigate around with varying outcomes.

from sys import exit

def money_room():
    print "There's plenty of money here. How much do you take?"

    next = raw_input("> ")
    if "0" in next or "1" in next:
        how_much = int(next)
    else:
        dead("Please type in something useful.")

    if how_much < 50:
        print "Nice. You're not greedy. You win!"
        exit(0)
    else:
        dead("You are greedy. You lose.")

def guard_room():
    print "There is a guard here."
    print "The guard has a magazine and is reading it."
    print "The guard is stood in front of a door."
    print "How are you going to get rid of the guard?"
    guard_moved = False

    while True:
        next = raw_input("> ")

        if next == "take magazine":
            dead("The guard takes out his gun and you're toast.")
        elif next == "distract guard" and not guard_moved:
            print "The guard has moved from the door.
            You can go through it now."
            guard_moved = True
        elif next == "distract guard" and guard_moved:
            dead("The guard gets annoyed and pulls out a gun.
            You know how this ends.")
        elif next == "open door" and guard_moved:
            money_room()
        else:
            print "I have no idea what that means."

    print "It is the room of insanity."
    print "Do you run for your life or simply bash your head against the wall."

    next = raw_input("> ")

    if "run" in next:
        start()
    elif "head" in next:
        dead("Well, that's the end of you.")

    exit(0)

def start():
    print "You are in a dark room."
    print "There is a door to right and left."
    print "Which one do you take?"

    next = raw_input("> ")

    if next == "left":
        guard_room()
