Jikuu Yuuden: Debias

Jikuu Yuuden: Debias is an action role-playing game for the Family Computer and Nintendo Famicom. Players control a warrior who undertakes quests for the local monarchy, battles monsters, and gathers clues and items from helpful non-player characters.

The game combines fantasy RPG exploration with side-scrolling hack-and-slash and platforming sequences. Its day/night cycle changes civilized areas, replacing wandering NPCs with monsters after dark.

A distinctive boxed item consists of two rune-marked circles used to decipher codes required for progression. The game was developed by Now Production and published by Namco, with a release date of November 27, 1987.
