Watch the attacks.
Sword slash is 1st panel.
Shield attack is 2nd panel.
And when he hit the ground with the shield it's the 3rd panel.
After the sequence, move to the panel in the given order and wait on it until he starts the move.

Pra quem está com dúvida como fazer, dá uma olhada nesse link, é um tutorial. Recomendo escrever a ordem num papel e ir com calma, você não precisa ficar pulando na plataforma, só ficar em cima parado, se a sequència for dois numeros iguais, saia da plataforma e suba nela novamente.

Ok, Facing toward the dude:
Sword wing= Left
Shield swing= Middle
Shield Smash = Right
He will perform 8 moves, then 3 moves where gold mist forms over the panels. These last three are to tell you what panel is which move.
Step onto each panel until the gold mist appears in the order of the first 8 moves demonstrated. Be sure to step off after the mist appears or it may double-tap.
