Bright Memory is a first-person shooter with melee elements. Players take control of Shelia, who, in addition to using guns and a sword, also has supernatural abilities such as psychokinesis and unleashing energy blasts. All forms of attack can be combined as desired and the game will award letter grades to creative combinations similar to Devil May Cry. Success in combat awards experience points that can be used to augment the character's skills and to unlock more abilities such as stopping time. Additionally, some areas feature puzzles that need to be solved.

Bright Memory was developed by Zeng "FYQD" Xiancheng using Unreal Engine 4 with development work taking place in the developer's spare time. Zeng first previewed the game in a trailer in 2017 and received financial support through Epic Games's Unreal Dev Grants.
