What to do

  1. Name the source saveIf it is a normal Steam Early Access save, Digital Sun says it carries into the Steam 1.0 release. Keep that claim scoped to the same Steam path.
  2. Open 1.0 on the same Steam pathUse the same Steam installation and account, then check the existing save slot. The evidence confirms carryover, not a manual file-copy procedure.
  3. Separate cross-platform from carryoverThe developer reply says cross-save is not implemented. That means no official shared-save system between PC storefronts or PC and consoles.
  4. Keep Steam Cloud in its laneSteam Cloud can synchronize compatible Steam installs. It is not a bridge to Game Pass, PlayStation, Xbox, or Switch 2.
  5. Protect exception savesA Steam thread reproduces a Digital Sun compatibility exception for demo and Expert-mode saves, and Digital Sun acknowledged the coverage. Treat those saves as outside the ordinary carryover guarantee and do not overwrite the original while checking.

How you know it worked

Your normal Steam EA save appears when you open 1.0 through the same Steam path. A missing slot on another storefront or platform is not evidence of a supported cross-save transfer, and an exception case should be checked without deleting the original.

Platform and version boundaries

ConfirmedA normal Steam Early Access save → Steam 1.0 carries over, according to Digital Sun.
UnsupportedCross-platform cross-save is not implemented, according to the developer reply.
Compatibility exceptionA Steam thread reproduces a Digital Sun statement that demo and Expert-mode saves are not compatible with pre-existing saves; Digital Sun acknowledged the coverage. Treat this as a bounded warning, not a universal wipe claim.
Secondary supportSteam Cloud documentation describes synchronization within Steam; it is not cross-save.
UnconfirmedAny local or platform-specific migration path, future cross-save support, and how an exception save should be repaired without the original.

Common failure branches

  • Stop and verify: Whether the compatibility exception applies to every historical Expert-mode save or only the mode's pre-existing-save boundary.
  • Stop and verify: Any local or platform-specific migration path that is not a cross-save feature.
  • Stop and verify: Whether future patches add cross-save after the checked developer reply.
Evidence note: The primary developer reply confirms Steam EA → Steam 1.0 carryover and no cross-save. A second Steam thread reproduces the demo/Expert compatibility exception and includes a developer acknowledgment of that coverage; treat the quoted exception as a boundary, not as permission to overwrite a save. Steam Cloud documentation provides secondary support for the platform boundary without turning cloud sync into cross-save.

FAQ

Does a normal Steam EA save carry into 1.0?

Yes. Digital Sun says Steam Early Access saves carry into the Steam 1.0 release, but a separate thread reproduces a compatibility exception for demo and Expert-mode saves that Digital Sun acknowledged.

Does Moonlighter 2 support cross-save?

No official cross-save is implemented according to the developer reply checked here.

Are demo and Expert-mode saves covered by the normal carryover rule?

Do not assume so. The compatibility exception is reproduced in a Steam thread and acknowledged by Digital Sun; keep the original save and treat the exact migration behavior as a boundary.

Is Steam Cloud cross-save?

No. Steam Cloud is synchronization within compatible Steam installs, not a shared PC/console or storefront bridge.
