02 / Rotations
Turn the world through W.
A rotation happens in a plane. In ordinary space you can turn in XY, XZ or YZ. Add W and three more planes become possible. Aetherfold’s main puzzles ask you to work with two of them, XW and ZW.
Interactive model / Tesseract projection
Try it
Two planes. Two turns.
Turn X toward W, then Z toward W. The diagram projects the whole shape. The game shows what intersects your slice.
What changes
The plane matters.
In XW, X and W mix while Y and Z stay fixed. In ZW, Z and W mix while X and Y stay fixed. In the diagram the XW rotation is applied first. Since both turns use W, changing their order can change the result.
In the game
Watch the bearing.
[ and ] snap XW by 90°. Hold Shift for 45°. Use , and . for 45° ZW turns. Press B to reset your orientation. The chamber compass shows the bearing you reach.
