Eternal Daughter is a freeware action-adventure game created by amateur developers Derek Yu and Jon Perry and released on June 21, 2002 under their former pseudonym Blackeye Software.
The gameplay of Eternal Daughter is based on a classic style of side-scrolling platform action, with added features such as secondary weapons and growth elements that are otherwise common in role-playing games: Items found throughout the game increase the strength of the player character's weapon or 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.
