Doraemon has been researching dinosaurs and using a time machine, he went to the primitive island in the Neolithic period. Taking a walk through the jungle, he treated them with interest without revealing their presence as long until I saw people who have trodden a herd of dinosaurs. People need to quickly save, until they finally trampled ichthyosaurs. Help the main hero of the game to cope with the task. Drive with the up-down-left-right to make a quick search and find the surviving man.
