Overview

In a Parallel Universe is a visual novel for players who like transformation fantasies with a playful, curious tone. It keeps things light while leaning into growth and body-change themes.

Story

Gwen wants to meet new people and become the biggest version of herself, in every sense. Her path leads her across different universes, where she runs into familiar faces from other worlds, each one tied to her growth.

Gameplay

Players guide Gwen through conversations and choices as she meets other characters and pursues her own transformation. Progress is tracked through individual paths and levels for Gwen and the other girls, with choices affecting how each one grows. The game includes sandbox-style exploration between story scenes, letting players decide who to visit and how far to push each character's development.

Features

Choice-driven growth paths for multiple characters, not just the protagonist
Option to play Gwen as female or futa
2D character art built around transformation and body-change themes
Parody elements woven into the cast of familiar faces

Installation

1. Extract and run.
