Doraemon

Doraemon is a video game adaptation of the popular Japanese anime of the same name, developed for the Famicom in 1986 by Hudson Soft. It was the tenth best selling Famicom game released in 1986, selling approximately 1,150,000 copies in it's lifetime. It is the third game created for the Doraemon license after the versions created for the Arcadia 2001 and the Epoch Cassette Vision.

In this game, Doraemon must travel through three different "Worlds" in order to rescue his five human friends who have been kidnapped. Each world is actually a different game with its own style of genre and game play system, and was designed by a different lead designer. The first World is an action game that takes place in a city that scrolls continuously in four directions. The second World is a shooter game that scrolls automatically in both horizontal and vertical directions. The third World is an underwater adventure game where each screen scrolls over to the next like in the original Zelda game.

Each world must be completed by defeating a boss at the end. Then you will advance to the next world, until all three bosses have been vanquished. Power-ups can be obtained in each world to increase Doraemon's strength and health meter. One power-up from the next world can be found in the first two world to give you an advantage when you finally arrive there. The game was never released outside of Japan. Even though the game is completely playable by a player with no knowledge of Japanese, ROM translator Neokid has released a patch to translate what little Japanese is present into English.
