The game does NOT respond to keyboard buttons. On smartphones, the
Pacman is supposed to follow your finger, to go in the direction
where you last tapped. In case that doesn't work, you have buttons
below the maze. On computers, it's playable by mouse. You can
see the source code, with the comments in Croatian, here. UPDATE on 24/03/2021: I have added eyes on the ghosts,
but that works only in Firefox. UPDATE on 27/03/2021: The eyes of the ghosts no longer rely
on the Firefox-specific SVG features. UPDATE on 27/08/2021: The server that SourceForge lets me use for free seems to
automatically insert (actually malformed by the HTTP standard) cookies into your browser
instead of using HTTP sessions when asked to use HTTP sessions (for highscores). I have tried
to solve that, but failed. If you are worried about being tracked using cookies, consult the
manual of your browser on how to delete those cookies. Or, better yet, use a browser that
automatically deletes cookies when they are no longer needed, such as the
TOR Browser (which protects from far more than just cookies).
Remember, it is much better to protect yourself using technology than to rely on laws.
