The introduction shows the Dungaga, an imperial industrialized race, conquering the more spiritual Lorian race. The protagonist, Mia, is the daughter of the Lorian priestess and an unknown father. Like the rest of her people, she is enslaved to do menial labor under the supervision of her half-brother Hume. As she sees her Dungaga stepfather Gar hit her mother, she manifests a light-based magic that she uses to strike down Gar. At her mother's advice, she flees the village.
In her travels, Mia meets the enigmatic lizardlike Shulin, the slime-based Grodol warriors, a familiar baby dragon named Elanduru, and several Dungaga dissidents. It is revealed that the Dungaga are controlled by the three sons of the dark god Baphomet, who wish to summon him into the world. After defeating the three sons, Mia must rally the free people of the world and obtain the blessing of the five gods, in order to strike out into Baphomet's realm and defeat him.
The gameplay of Eternal Daughter is based on a classic video game style: side-scrolling platform action, but with added features such as secondary weapons and growth elements that are otherwise common in the genre of role-playing games. Items found throughout the game increase the strength of the player character's weapon, or the player's maximum number of health points. Also, as the game progresses, the player gains new abilities that can be used to explore areas of the game that were previously unreachable, progressively "unlocking" new locations within the game world.
Because of this combination of gameplay elements, comparisons are often drawn to Castlevania: Symphony of the Night and Super Metroid, popular console games that feature the same type of platform action combined with exploration-based adventure. These type of games are often called Metroidvania.
A large part of the music was composed by Swedish video game composer David Saulesco. Like the game itself, the score uses a number of influences from famous video game soundtracks, most notably Final Fantasy VII. Eternal Daughter was Saulesco's first video game soundtrack, produced when he was 16 years old. The soundtrack was released on Saulesco's Bandcamp under the Creative Commons license CC by-nc-sa 3.0 on January 11, 2011.
Home of the Underdogs praised Eternal Daughter for its well-designed and smoothly animated characters, precise platform engine, and addictive nonlinear gameplay. 1UP highlighted the game's unique visual style and level of polish, not usually seen in freeware games. Both reviews commented on Eternal Daughter's "harsh-but-fair" difficulty level. In 2006, 1UP.com included Eternal Daughter in a list of the 101 best free games on the Internet.
