f'(x)
The hardest N64 game ever. It's like a video game version of a nightmare. You play it, and you don't want to go back to sleep.
I played F-Zero X and I said, 'This game is harder than my math homework.'
F-Zero X is like a game that makes you question your life choices.
That game is so hard, my brother said it was harder than getting a tattoo.
