Lust Survivor is a Ren'Py adult adventure by Moccasin's Mirror, presented with 2D CG art. Seven students from different fields are heading to a distant research site when an accident strands them on an empty planet. You guide all seven women, deciding how they cooperate, survive, and seek rescue while learning to manage attraction and personal limits. A willpower system tracks choices: acting in line with a character's usual nature can restore willpower, while forcing her to behave differently drains it. The story includes sci-fi survival, relationship choices, and multiple endings.
The current release is v1.0.1, dated May 1, 2025, for Windows, Linux, and Mac, with English text and no censorship. Development is ongoing. The latest changelog entry adds smaller scenes and fixes sprites. Earlier updates expanded Route B, added new backgrounds, item images, music, dialogue, and scenes, and corrected animation or character display issues.
Developer's description
Seven girls crashland on an uninhabited planet after an accident, they will have to survive until help arrives and learn how to deal with each other. Hours ago the girls were just students from different careers on route to a far away research site for different reasons. Some girls know each other but nobody was remotely prepared for the situation. The group needs to start getting along and doing something if they want to get rescued or at least survive.
Spoiler
In Lust Survivor the player takes control of the 7 girls and makes decisions for them. There is one issue: not all of them have the willpower to make the correct choices! Lust Survivor has a willpower system where taking the choices the girl would normally take rewards you with “willpower points” and going against their nature costs willpower. That means, even if the correct choice is very easy to spot, you might want to pick the bad one to conserve willpower.

Mostly DOWNGRADE from last game of this dev. So much inconsistent art, so sad for me that dev falling for AI SLOP. The characters so hot ( hope not ai generated) but rest of art in the game are very…
ScrewMe2024-12-02★★★★★
Man, I'm still surprised how little of a discussion of this game there is. The concept with character traits used is cool af. It's probably similar to the way how your typical variables work in "usual" type of VN, but…
