You can add an absurd amount of lag into the game by holding left, right, and up. you can still cast spells, and seems to me to affect enemy movement and not spell cooldown. Just sayin'.
Fun glitch: If you hold boost before and through the cutscene where you get to the moon, you'll get a phantom, permanent boost while you're in space additional to your normal one.
