About this game
The world has been devastated by a mysterious virus.
Cities collapse, nature twists, and humanity is pushed to the edge — yet hope still lingers.
In Nyx: Legacy, you follow Lyn, the protective older sister, and Nyx, her reckless yet fearless younger sister. Together they fight for survival in a world where danger is everywhere.
Features
Emotional Storytelling: Experience a heartfelt tale of sisterhood filled with hope, despair, and determination.
Classic RPG Feel: Inspired by Lufia I & II, with a modern twist on puzzles, dungeons, and exploration.
Engaging Gameplay: Balanced mix of exploration, combat, and story progression — never just filler.
Mutated Monsters: Face enemies shaped by bizarre and unexpected mutations, each designed to surprise and unsettle.
Replayability: Unlock New Game Plus and dynamic difficulty options for a fresh challenge after completing the story.

Nyx Legacy - update
Hey guys,It’s been nearly 2 months since the last update on Nyx Legacy. Last time, I showed a bunch of reworked dungeons — this time, I’ve got much bigger news.First of all: Nyx is absolutely still being worked on. I just haven’t been talking about it much lately.Not because the passion is gone — quite the opposite. The more I talk about it, the more excited I get… and that excitement makes me rush things. I want to show you what the game really is, but the demo already taught me a lot. Even though it was received well, I found many things I want to do differently.That means rethinking how I build systems — making them more intuitive, more important, and more natural to use. Also improving how tutorials and explanations are handled. I’m also excited to tell you that Anna will be helping design the world and maps.This will naturally add more variation to how things look and feel, but she’s incredibly good at bringing environments to life. This change will speed up development a lot, because it allows me to focus on what I enjoy most: debugging, balancing, redesigning systems, adding puzzles, and expanding the story — without constantly switching back to world-building. I’ve also created a roadmap for myself.I don’t really need one — most of the game already lives in my head — but it helps me stay structured, finish things properly, and make things clearer for the team.I won’t be sharing the roadmap, since it contains major spoilers. I’ve considered making a public version, but honestly, I’d rather spend that energy actually working on the game and talking to you directly. So… what’s actually been done?Finished building Herobus, a very fun cityCompleted a large chunk of the overworldFinished most of the storyPre-built 3 new dungeonsPre-built 2 new citiesPre-built a big secret 👀 Changes & ImprovementsRemoved the hotkey bar (too complicated and unnecessary)Removed overworld skills from the main skill listAdded a Techniques menu for overworld abilitiesAdded new sprites f...Read full article on Community Announcements (Rattacookie)Patch NotesOfficial
