Inside Untangle
Separate crossing edges by moving their endpoints. Spread the outer vertices before fixing a tight knot in the middle. Drag a vertex to a new position; keep adjusting until no edges cross.
The game retains its English interface. Its own menus and tutorial describe the current release.

Session notes.
Pause, reload & saved progress
Pause using the game’s own controls before leaving. SENOVIRA cannot reliably pause or mute an external game. Reload restarts the frame and may discard unsaved progress; Unload removes it. Neither clears the game’s storage. Browser privacy settings may separate embedded and direct saves.
