Eggerland

Eggerland is a puzzle/strategy game developed by HAL Laboratory for the Famicom Disk System in the beginning of 1987. The game is often referred to as "Syodai" (初代), or the "first Eggerland." The game is a remake of "Meikyuu Shinwa" (Eggerland 2; lit. "Labyrinth Myth") for the MSX Home Computer System with updated graphics, different music, and twenty-two additional stages (the game features a total of 122 stages). The Eggerland series is better known outside of Japan as The Adventure of Lolo series.

In this Eggerland, Lolo must navigate his way through a non-linear series of rooms, the majority of which occupy a 10x10 arrangment along the main floor of a castle. Many rooms have more than one exit for Lolo to choose from, and a map can be collected along the way to provide the player with information about where he or she is, and what rooms have already been visited. Secret entrances to hidden chambers must be found so that keys can be collected, enabling the player to explore deeper into the castle.

Story
Peace lasted for many years in the beautiful realm of Eden Land. The people were at peace and everything was well. However, one day the incarnation of destruction, King Egger, came from the underground realm of Eggerland seeking to destroy the peaceful realm and claim it for himself. King Eden dispatched Lala to the God Inphony to seek his help, and Inphony gave her Inphonit Power and five keys to open the gate of evil. Four gods obeyed Inphonit and joined her, but Egger caught her while she tried to stop him and concealed her in his underground labyrinth of Eggerland. Fortunately, she succeeded in concealing the Inphonit Power, and Five Keys and Four Gods in the land of Eggerland. Lolo, prince of Gentle Land, heard the news that Lala had been captured and immediately ran to Eggerland to rescue her.
