- Order of the Sinking Star mirror puzzle revolves around teleporting across water using pushable mirrors
- Mirror rule: stepping into a mirror transports you to the tile directly opposite it
- Mirrors can be pushed like blocks, but never rotated, so placement is everything
- Clone mechanic: aligned mirror pairs duplicate you, and clones move in tandem
- Undo and reset freely: hold Z to undo, R to return to the checkpoint
How the Mirror Puzzle Works
The mirror puzzle is the signature mechanic of Order of the Sinking Star's open-world islands. Each island is surrounded by water you cannot swim across — fall in and you drown, resetting the level. Mirrors let you cross: when you walk into a mirror, you are instantly transported to the tile on the opposite side of it. Because mirrors themselves can be pushed across the grid like Sokoban blocks, every puzzle becomes a question of positioning the mirror so its "opposite side" lands where you need to go.

A mirror only teleports you when you step into it from a walkable tile. The destination is always the tile directly opposite your entry point. If that tile is water, you drown — so check where you will land before committing.
Mirror Puzzle Mechanics Reference
Every island introduces a twist on the basic teleport. The table below summarizes the core elements you will encounter.
| Element | Behavior | Puzzle Use |
|---|---|---|
| Mirror | Teleports you to the opposite tile; pushable, not rotatable | Crossing water gaps of any width |
| Push block | Standard Sokoban block; sinks in water to form a platform | Building bridges and stepping stones |
| Aligned mirror pair | Creates a duplicate of you when both are in line | Multi-switch puzzles needing simultaneous presses |
| Clones | Move in tandem with the original; blocked clones stay put | Separating clones by pinning them against walls |
| Pink/yellow cubes | Can travel through mirrors like the player does | Delivering objects across gaps you cannot cross |
| Checkpoint | Saves progress; R returns you here | Recovering from drownings cheaply |
You cannot mirror objects freely — only the player (and special colored cubes) pass through mirrors. Standard blocks must be pushed the long way around, or dropped into water to create platforms.
Movement Basics
- Hold Shift to run
- Hold Ctrl to slow-walk for precision
- One tile per step on grid islands
Error Recovery
- Hold Z to undo any number of moves
- Press R to restart from checkpoint
- Undo even reverses a reset
Mirror Handling
- Push from behind only
- No rotation — plan orientation early
- Reset a mirror with X if misplaced
Step-by-Step Solving Method
Follow this repeatable process for any mirror island. It prevents the most frequent dead ends, such as pushing a mirror into a corner or trapping yourself behind a block.
Survey the Island
Identify your goal tile, count the water gaps, and note every mirror and block. Decide which gap actually needs a mirror versus a block platform.
Plan Mirror Placement
Since mirrors cannot rotate, determine the final row or column the mirror must occupy so its opposite-side output lands on solid ground across the water.
Position Yourself Behind the Mirror
You need a walkable tile behind the mirror to push it. Use blocks as temporary platforms to reach pushing positions that are otherwise unreachable.
Push Blocks First, Mirror Last
Arrange blocks and stepping stones before committing the mirror. A mirror pushed into a dead corner usually forces a full undo chain.
Teleport, Verify, and Advance
Step into the mirror, confirm you land on the intended tile, and move toward the exit. If you drown, hold Z to undo instead of restarting the level.
Blocks are flexible — they can form platforms anywhere in water. Mirrors are rigid — their output tile is fixed by position and orientation. Solving block logistics first means the mirror's placement is the only remaining variable.
Clone Puzzles and Dual Mirrors
Later islands place two mirrors in a line, creating a duplicate of the player. Clones move together: when you step, every clone steps the same direction unless blocked. This enables simultaneous button presses but introduces new failure states.
| Clone Scenario | What Happens | Recommended Response |
|---|---|---|
| Clone walks into water | Clone is lost | Undo immediately; realign mirrors |
| Clone blocked by wall or block | Clone stays, others move | Use walls to separate clones on purpose |
| Too many clones created | Extra clone blocks a switch | Break mirror alignment before duplicating |
| Clones needed on both switches | Press both simultaneously | Space clones one tile apart in tandem |
The key technique is pinning: push a block or use terrain so one clone gets stuck while the original keeps moving. This lets you stagger clone positions until each stands on its own switch. Misaligned duplicates are the number one cause of soft-locks on these islands, so undo early and often.
Clones only mirror your directional input. If a clone is blocked, it simply stays behind while the rest of the group advances — this is the intended tool for spreading clones across different rows and columns.
Explorer's Checklist and World Tips
Between puzzle islands, the open world rewards careful exploration: lore entries, travel shortcuts, and warning signs about difficulty spikes. The opening NPC advice holds true for the whole map — progress north and east first, and avoid the west until your mirror skills are sharp.
Mirror Island Checklist:
- Solve the first four intro islands to unlock fast travel
- Collect every lore book entry on the starting continent
- Master undo (Z) and reset (R) before harder islands
- Complete one dual-mirror clone puzzle without drowning
- Photograph the shield sigil clue: square, circle, and diamond
- Attempt the western challenge island only after all core mechanics
| World Feature | Location Hint | Reward |
|---|---|---|
| Fast travel points | Unlocked after island puzzles | Skip re-solving completed levels |
| Lore plaques | Scattered on every island | Story of the mirror merchant |
| Numbered sigils (069104) | Title-screen style murals | Likely relevant in later areas |
| West region | Beyond starter islands | Serious challenge — advanced puzzles |
| Super scary level node | On the island map screen | High-difficulty optional trial |
Once an island's puzzle is solved, a transport node appears that lets you travel between areas without redoing the puzzle. Always finish an island fully before moving on so you keep the shortcut.
Frequently Asked Questions
Q: What is the Order of the Sinking Star mirror puzzle rule?
Step into a mirror and you teleport to the tile directly opposite your entry point. Mirrors can be pushed around the grid like blocks but never rotated, so solving means positioning each mirror so its output tile is the ground you need to reach.
Q: Can I undo a mistake in a mirror puzzle?
Yes. Hold Z to undo moves one at a time, including after a drowning or even after a full reset. Pressing R returns you to the last checkpoint, and pressing X can reset a misplaced mirror or block to its original spot.
Q: Why do I keep creating extra clones?
Two mirrors aligned in a straight line duplicate you when you pass between them. To avoid unwanted clones, break the alignment by pushing one mirror out of line before walking through, or pin clones against walls so they stop following your movements.
Q: Can objects pass through mirrors?
Standard push blocks cannot. Only the player and special colored cubes (pink and yellow variants found on later islands) travel through mirrors. Regular blocks must be pushed around terrain or dropped into water to form platforms.
Every new island teaches one new mechanic. If a puzzle looks overwhelming, identify the single new element first — the solution almost always combines it with the mirror teleport rule you already know.
