Usage

Structured Editor

The structured editor provides an intuitive interface for editing game values:

• General: Modify basic values like antimatter, infinities, eternities, records, and more

• Dimensions: Edit antimatter, infinity, and time dimensions with their amounts and multipliers

• Replicanti: Control replication chance, interval, galaxies, and toggle unlock status

• Infinity: Manage infinity points, infinity power, and related values

• Eternity: Control eternity points, time shards, theorems, and studies

• Dilation: Adjust tachyon particles, dilated time, and black hole settings

• Reality: Edit reality machines, imaginary machines, and perk points

• Automator: Edit the scripts and constants saved by the game, inspect execution state, and browse the pinned in-game command reference. Script text is preserved but not compiled by the editor.

• Glyphs: Modify glyph level cap, sacrifice values, and cosmetic settings

• Achievements: Unlock all achievements or secret achievements with a single click

  • Celestials: Fine-tune all celestial-related properties for each of the seven celestials
  • Challenges: Inspect upstream completion bits individually or complete all known Normal/Infinity Challenges with the exact game masks
  • Bits & collections: Edit upstream progression, celestial, glyph, interface/news bitfields and Set-backed collections while preserving unknown values

• All values: Search every object, array, and leaf found in the loaded save. Fields marked Discovered are inferred from the current document and remain available even when the structured registry has no dedicated definition yet.

To complete every known bitfield challenge, open Challenges, choose Normal Challenges or Infinity Challenges, then click Complete all known. Challenge ids are one-based bit indexes: Normal Challenges 1-12 use mask 8190, and Infinity Challenges 1-8 use mask 510; bit 0 is unused. Unknown or future bits are preserved. Eternity Challenge completion is not a bitfield: set eternityChalls.eterc1 through eternityChalls.eterc12 to 5 in the Eternity section to mark all five completions for each challenge.

The detailed index and compatibility notes for the new bitfield/collection controls are in docs/bitfields-and-collections.md and docs/upstream-compatibility.md.

JSON Editor

For advanced users who need direct access to the save file structure:

• View and edit the complete save file in JSON format
• Full control over all game variables
• JSON validation and formatting

Settings

Customize your editing experience:

• Choose default editor view
• Enable/disable confirmations
• Switch between display modes
• Configure advanced options

Compatibility and backup boundaries

The editor supports the documented PC, Android, and iOS save transport envelopes at the codec and fixture level. The iOS fixture is derived from a real iOS export, re-encoded by this editor after scrubbing the one identifying string; it is not shipped as the raw payload. Mobile transport support is not a claim of PC-to-mobile conversion or compatibility with every live Android or iOS game build. An internal round-trip does not prove that a real save will load in the game; use an untouched backup and perform a manual import/export check before relying on an edited save. The editor does not apply upstream save migrations automatically.
