Marsarah Tweaks
Version: 1.8.3 Author: Marsarah
🧰 About the Mod
Marsarah Tweaks is a modular and optimized port of my previous project, MarsarahMod. It features numerous code improvements, cleaned-up logic, and ServerSync integration. This mod changes many aspects of the game so it's advised to look through and read the description or the config file, to decide which features to enable and which to turn off. Each feature is grouped into sections to make this process easier. In addition, the mod scans for already installed mods and automatically disables its own relevant configs if it finds mods that are incompatible or that may cause issues together. If any issues or incompatibilities are found, please post them on the mod's Nexus page.
⚠️ Upgrade Note: The custom build pieces and UI features previously included in Marsarah Tweaks have been moved into their own standalone mods. MarsarahBuildPieces now contains the Pocket Portal, Extra Lights, Glacial Stone Portal, Mystical Light Ward, and other custom build-piece functionality. MarsarahUI now contains the UI features previously included in Marsarah Tweaks. Both mods are optional and Marsarah Tweaks can still be used on its own.
If updating from an older version of Marsarah Tweaks that still contained the custom build pieces, make a world backup before updating and install MarsarahBuildPieces if you want to continue using those pieces.
Development Notes
Deep North / Spoiler Note: Deep North content is intentionally not included in Marsarah Tweaks yet. I want to experience the new biome, progression, gear, build pieces, and other content myself before digging through the game files, so I can play through it without spoiling the experience for myself. Once I have played through the Deep North, I plan to update the mod to properly include its content across the relevant features, including things such as gear and recipe changes, build-piece costs and materials, progression and balance adjustments, and any other existing tweaks that should apply to the new content.
AI Usage Disclosure: Marsarah Tweaks grew out of my original MarsarahMod project, whose code I initially wrote myself. AI tools were later used to assist with porting that code into Marsarah Tweaks and are now used as part of my development workflow for tasks such as debugging, refactoring, compatibility updates, researching game API changes, and documentation. Development remains human-directed: I decide what features are added, how they should behave, and I write code, review and test the changes included in releases. The mod's logo was also created using generative AI.
