Overview

The Solarion Project is a 2D animated visual novel for players who want a sci-fi crew of monster girl companions and a slow-building romance focus. The tone stays personal and character-driven rather than pure spectacle.

Story

After inheriting a starship from a father he barely knew, the protagonist sets out across the galaxy with an all-female crew, hoping to build something like a new family. As the journey continues, buried details about his father surface, unsettling truths that even the crew who once served alongside him never suspected.

Gameplay

Play unfolds as point-and-click exploration mixed with dialogue-driven visual novel scenes. Each crew member has her own backstory to uncover, and conversations let the player steer toward friendship, romance, or something shared among several companions. Choices carry weight, some leading to good outcomes and others to loss, keeping the crew's fate in the player's hands.

Features

Distinct, fully written companions with individual personalities and histories
Animated 2D scenes tied to character progression
Branching dialogue choices with real consequences, not just flavor text

Installation

1. Extract to desired location. 2. Run "TheSolarionProject.exe"

Changelog

v0.33

New Content:

Catsuki Progression (3 animated scenes, +1 nonanimated, +kiss) - Triggered after Shuma is completed

Major Changes:

MAJOR SAVING REWORK!
Save location is now changed to be inside your user appdata folder. This means you won't have to move save files between each new version.
It is located inside \Users\{User}\Appdata\Local\The Solarion Project
It is still best to save a separate slot every now and again as a backup
Relationship locking system
A system that will be used in the future, but also appears in Catsuki's progression
This simulates the passage of time, instead of events instantly triggering after returning to the ship, they can be locked until enough time has passed
Time in this context is whenever you use the ship to travel to a planet, this will count as a passage of time
Updated character dialogue busts for all characters
Kittenna, Shelly & Catherine have all become less thick
Malaena's will be updated in the future
Everyone has gotten slightly taller (or rather they have been pushed upwards showing off more of their image)

Battle System Changes:

Behind the scenes: All load out menus / UIs now are in separate dedicated plugins as opposed to being drawn on the game map. Should be a lot smoother for any bug fixing / edits / additions that need to occur in the future
Loadouts can now be created (and are saved automatically whenever you leave the menu or change to a different loadout)
Malaena & Catherine animated sprite battler added, Shelly non-animated sprite battler added
Still don't recommend using Malaena, Catherine or Shelly just yet
Lots of new memory core unique effects added
Renamed "Hold" cards to "Aim" cards instead
Characters now have a "Special Gauge Gain" stat. Which is how much their special gauge increases when they make an attack. This is also affected by the selected Combat card for the character.
Advance cards generate the least amount (Stat X 1)
Aim cards generate an average amount (Stat x 3)
Cover Cards generate the most amount) (Stat X 6)
