Order of the Sinking Star official cover art

A spoiler-safe way to approach a stuck puzzle

Quick answer

The game’s nonlinear structure lets you leave a difficult puzzle and return. Use that freedom to test one clear idea at a time.

October 17: reset regression remains open

The developer says October 16’s update can leave Reset failing to restore a level correctly. Its temporary workaround is Undo all the way back to the start, after which Reset should work. Long levels may need substantial undoing; the note promises no recovery of lost progress. Kingy has not tested this workaround.

The October 16 r67255 update addresses crashes or oversized save files after repeated resets following a pushed rock or redirected river. October 17 r67271 separately corrects a missing lily and transmutation/quit/re-entry character-switch failures. Do not treat these notes as verification of every older recorded route.

A practical observation routine

The following is an editorial solving routine, not a guaranteed solution. It is designed around the developer’s description of interacting puzzle systems.

  1. Name the visible goal without guessing the solution.
  2. Write down which hero and objects are present.
  3. Test one interaction and record the exact result.
  4. Separate an observed rule from a possible explanation.
  5. If your next attempt has no new idea, explore another available branch.

Can I undo an accidental puzzle reset?

Zachary Dalton’s June 10 hands-on reports rewinding a level restart. Steam Deck HQ separately describes move undo and puzzle reset. These June preview observations have not yet been tested on current builds by Kingy.

The October 9 full-game update reports a fix for Undo sometimes not working on the Rover. It does not establish the scope of undo after every reset, save reload or completed puzzle. Record the action sequence and current build if the expected state still does not return.

The October 12 notes also say a wizard overworld change can leave a player inside a wall; use Undo to return to a valid position. This is a specific developer workaround, not a universal save-recovery method.

  1. Identify your build’s Undo/rewind control; button bindings are unconfirmed here.
  2. After an unwanted move, use Undo and compare hero and object positions.
  3. After an accidental puzzle reset, try Undo before making further moves. Check whether the pre-reset arrangement returns.
  4. If the expected state does not return, record the room, build and action sequence before trying more changes.

What to record before leaving

Use My progress to keep a puzzle notebook. Record a visible room label or a location description of your own, the last useful observation and the next test you want to make. Avoid inventing a room number that could be mistaken for an official identifier.

How to use the puzzle hints

Find a matching starting layout in the Mirror Isles atlas. Each room has two separate hints and a full route, all initially closed. The complete route includes timestamped gameplay for checking exact positions. These are observed June demo solutions; Kingy has not independently replayed them in the native game.
