Doki Doki Panic
Doki Doki Panic is a Japanese video game released for the Famicom Disk System about a family who plans to rescue two children. The full title is Yume Kōjō: Doki Doki Panic (夢工場：ドキドキパニック), translating to "Dream Factory: Doki-doki (sound of beating heart) Panic". The game takes place within a book with an Arabian setting. There are four playable characters, and the game is not completed until you play through as all four.
The game was made in cooperation with Fuji Television, which had a tie-in cartoon show.
The game known in North America and Europe as Super Mario Bros. 2 and known in Japan as Super Mario USA, was developed by adapting this game. The four characters in the game were replaced by Mario, Luigi, Princess Peach, and Toad. Most of the other differences between the two are small graphical changes, such as animation being added to the POW blocks, cherries, and vegetables for the Mario version, mushrooms replaced hearts as health boosters, and the characters shrink when reduced to only one unit of health. The save feature was also taken out of the NES version of Super Mario Bros. 2, due to limitation of the NES system compared to the Famicom Disk System, but it was brought back on the Super Mario All-Stars version of Super Mario Bros. 2.
"Doki doki" is a Japanese onomatopoeia for a rapidly beating heart. It is commonly found in Japanese video game titles, carrying connotations of excitement and anxiety.
