Overview
A Simple Life with My Unobtrusive Sister is an action-adventure roguelike for players who want dungeon combat mixed with slower domestic scenes. The tone shifts between grim survival and quiet moments at home.
Story
An adventurer descends into the Abyss alone, searching for the materials to brew a cure called "red cerebrospinal fluid" for his sister's special condition. He works against a deadline: if the elixir isn't finished in time, her condition will take its course. Each trip into the dungeon is both a supply run and a race against that clock.
Gameplay
Runs combine roguelike dungeon crawling with open-world exploration, sending the player through the Abyss to fight monsters and gather elixir ingredients before returning home. Between expeditions, the game shifts to a sandbox-style home life with the sister, where relationship moments and side activities fill the time before the next descent. Combat, scavenging, and domestic scenes repeat in a loop tied to the elixir deadline.

- Special equipment and unique enemy types to find during runs
- Animated character art with varied expressions and poses for key scenes
- A home-life sandbox layer that runs parallel to the dungeon loop
