Overview
Intimate Days with My Tsundere Sister is a visual novel-style adult sandbox for players who like slow-burn taboo romance set in close quarters. The tone stays intimate and quiet, favoring tension over spectacle.
Story
Left alone in the house for a month, the protagonist watches his usually cold sister soften when no one else is around. What starts as suppressed longing turns into a deliberate choice to cross a line he can't take back, all while other women in his orbit make their own intentions toward him clear before the month runs out.
Gameplay
Play unfolds as a day-by-day sandbox: managing time, exploring locations that open up as the month progresses, and building trust or desire with the women living around the protagonist. Choices shape which relationships deepen and which scenes unlock, leading toward one of several possible endings once the thirty days are up.
Features
- Animated 2D scenes paired with voiced audio for key moments
- A cast of women with distinct routes converging around a shared household
- Multiple endings based on how the month-long cohabitation is handled
Installation
