ghost house strategy is tough to do optimally. if you delay (turn back, crouch for a little) after the first boo line loads, the first jump becomes easier. to get the spin jump off the second boo line, try to land far to the right side of the leading boo, so you wont take damage. then, since you still have firepower, you can use the risky strat in chocolate secret, and if you get hit by a football you still save time.
