"レミリアいじり　追憶のピース【東方】" is a free simulation game developed by ISY for the Android platform. In this game, players take on the role of a being responsible for restoring the memories of a character named レミリア.

After falling down the stairs and losing most of her memory, レミリア wakes up in a spiritual world. It is up to the player to help her remember various events and words. However, due to the confusion in her memories, she may mistake false information as her own.

Players have the freedom to either continue telling レミリア the truth or teach her random things. As she recalls words and memories, レミリア will talk about different events, but it is important to note that her memories may not always be accurate.

Throughout the game, players must collect "ピース" (pieces) of レミリア's shattered memories to assist in recovering her memory.

Please note that this game is a secondary creation of the Eastern project and includes credits for some sound effects and background music.
