Field notes
The control guide distinguishes desktop inputs (WASD, mouse, click, Shift, and Space) from touch inputs such as swiping and holding on-screen controls. Its match interface also includes private room codes, host-started matches, rematches, and a KO Points tally; the extracted text does not establish whether those features were functioning during the probe.
