The settings menu is short and every item in it does exactly one thing. This page goes through them.
Language
Turkish and English. Changing it affects interface text only — the game itself already tells its story without words, so you can play a level just as well in a language you do not read.
Reduced motion
Stops decorative animation; the transitions that show you what the board did remain. It does not change play. The detail is on Accessibility.
Threat highlight
Decides whether lines of sight are painted on the board. It starts on in act 1 and can also be toggled with a single tap; this setting holds your lasting preference.
Turning it off does not affect stars.
Text size
Enlarges menus and tutorial lines.
Sound and music
Two separate sliders: effects and music are set independently and either can go to zero.
The ambience changes by act — the murmur of the bazaar, desert wind, mountain echo — and footsteps differ by surface. The capture sound is deliberately soft: it is meant as a "hmm", not a punishment.
Haptics
A short vibration on mobile when you move and when you are caught. Can be turned off.
Exporting and importing your save
Export gives you a copy of your save as versioned JSON text; you can copy it or download it to a file. Import reads that text and, if it is valid, puts it in place of your save.
Invalid text changes nothing — your save cannot be corrupted by a half-finished import.
Why that is the only way to move a save is on Offline and saves.
