You can leave the enemy where he is. Go nearly to the gold at the bottom right. Do not pick it up yet, but go up and get the two nuggets at the top left. Then you can come back down to where you were and complete the level.
Pots deixar l' enemic on es troba. Vés gairebé fins a l' or de la part de baix a la dreta. No l' agafis encara, sinó que puja i agafa les dues llavors de la part superior a l' esquerra. Aleshores pots tornar on estaves i completar el nivell.
