About Growing My Grandpa!
Growing My Grandpa! is a story-driven game about Adrienne, a shy and intensely introverted girl living in an unhappy home. In a trash-strewn basement that appears to have been the site of a strange scientific study, she discovers a secret that defies ordinary biological explanations. After making a desperate wish, Adrienne begins raising a powerful entity she calls Grandpa. The story takes about 90 minutes to play.
Raising Grandpa
Grandpa grows when you feed him and can hold conversations when you speak with him. You also educate him and try to keep him content, while learning that he follows a strange and deadly logic. To have a chance at a happy life, Adrienne must uncover the basement’s secrets.
Story and atmosphere
The story explores the pain of desire, the weight of loneliness and the need for intimacy. Its dense lore brings together science fiction, sympathetic magic and speculative neuroscience, presented with unsettling FMV-inspired graphics and an atmospheric soundtrack.
Endings
The game has two very different endings, shaped by your understanding of the lore and your interactions with Grandpa.
