There is nowhere to dig, so you must dodge the enemies and avoid falling to the concrete at the wrong time. Try to keep the enemies together. If an enemy has gold coloring, he is holding a nugget. He might drop it as he runs over the concrete or maybe at the top of a ladder... patience, patience!
Ez dago zulatzeko lekurik, beraz etsaiei iruzur egin eta hormigoiera erortzea ekidin behar duzu. Saiatu etsaiak batera mantentzen. Etsai batek urrezko ingurune bat badu, pipita bat duela esan nahi du. Erori egin dakioke hormigoian korritzen ari den bitartean edo eskilara batean dabilela... Pazientzia!!
