Overview

Lust Reaction is a life-sim sandbox for players who enjoy slow-burn character progression alongside everyday management. The tone stays grounded, favoring routine and personal growth over high drama.

Gameplay

Starting out from your parents' house, you manage daily routines, raise your stats, and move through a world with places like the University, City Center, and various local businesses. Earnings and reputation gained along the way let you acquire property and take over businesses, giving your daily loop more weight over time. Alongside this, a dedicated interaction system lets you approach the game's cast individually, with each relationship advancing through its own quest line.

Features

A cast of characters with distinct personalities, fetishes, and intimacy that develops gradually
Option to choose your protagonist's gender and name, with adjustments possible later in the game
Property and business ownership tied directly to your daily progress
Animated 2D presentation throughout

Installation

Extract the .zip file. Run LustReaction.exe.
