It was originally released in 1987 in Japan only under the title Hydlide 3: The Space Memories (ハイドライド３ 異次元の思い出, Haidoraido 3: I Jigen No Omoide) for the MSX, MSX2, and PC-8801mkII SR.

[3] The game was developed by Hydlide series veterans T&E Soft and released worldwide on the Sega Genesis / Mega Drive on October 6, 1989, in Japan, early 1990 in the United States, and 1991 in Europe.

Like its predecessor Hydlide II: Shine of Darkness (1985), the player has a morality meter that can be aligned with either Justice, Normal, or Evil.

[4] The game also features an in-game clock setting day-night cycles, where the character must eat two times a day and sleep regularly.

The game uses cut scenes for its opening and ending sequences, a combat system similar to Ys, a choice between four distinct character classes, and a wide variety of equipment and spells.

GamePro gave a positive review, citing the varied experiences offered by the different playable characters, the morality system, and the inclusion of four save slots.
