- Configuration files for balance, world, boss encounter, navigation and visuals.

Known limitations of this preview

- The Meridian Key that opens the Gate of Hours cannot be earned in survival yet (the Observatory that grants it is not finished). Operators can use `/give @s astrarium:meridian_key`.
- The mini-bosses and the clockwork and starborn creatures other than the Cinder Wisp are not placed in dungeons yet; they appear only through spawn eggs or commands. Because of that, items that drop from them (Chart Fragments, Lens Crystal, Gear Core, Ember Core) are not obtainable in survival yet, and neither are the items crafted from them.
- Most of the planned structures (Clockwork Cistern, Lenswright's Spire, Cinderforge Deeps, Vesper Waystone, Umbral Reliquary) are not in this version.
- The Archon fight is not balanced yet for survival play or for groups.
- Not tested with other mods, in multiplayer or on a dedicated server with players.
