I've seen a few threads with a similar issue but not one the same, apologies if there is one already.

I'm currently having a problem where I'm unable to progress through the game after the mutant cousin Kyle fight.

I get through the fight ok, it's when I have to press buttons in the fart sequence where I get to the same stage have both thumbsticks pointing inwards) only for it to not change and therefore I guess not complete?

Any known way to fix this or any advice?
