Penguin Land

source: wikipedia_enPenguin Land, known as Doki Doki Penguin Land Uchū Daibōken in Japan, is a 1987 puzzle-platform game published and developed by Sega for the Master System. It is the second game in the Doki Doki Penguin Land series. The player controls a penguin to guide an egg around polar bears, rocks and other hazards. There are 50 stages and a level editor which can save up to 15 additional levels. The level editor data is stored on the game's battery back-up RAM. Penguin Land was the first home console video game to include a battery backup save feature, its original Japanese version being released four days prior to The Legend of Zelda's US release.
