le terrain se degrade a mesure que la partie avance, evitez de tomber
dans la lave avant les autres !

a chaque deplacement, vous rendez l'ancienne place instable, qui se
deteriorera a son tour !

faire un long saut fissure egalement la case ou vous atterissez, donc
faites attention si vous sautez sur une case deja fissuree !

le dernier en vie gagne la partie.")
