Rainy Hall is the first map in every category in the game.
Quitouts[]
In quitouts, you'll want to start doing diolauge skips as soon as the first line of diolauge starts (4 to be exact). By doing this, the game freaks out and starts speeding through the different sections, making it hard to set up boosts and open doors.
Everything else[]
Since you can't do dialogue skips, you can use the time in the intro to set up boosts by putting knight helmets on the ground, and opening the door at the bottom of the staircase.
