About Growing My Grandpa!

Growing My Grandpa! places you in the role of Adrienne, an introverted girl living in an unhappy home. In a trash‑strewn basement that feels like a forgotten scientific lab, she discovers a secret that defies ordinary biology.

With a desperate wish she begins raising a powerful entity she calls Grandpa. Feeding and teaching the entity drives the story forward, and the game’s dark, dense lore leads to one of two very different endings after roughly ninety minutes of play.
