Neave Pac-Man was my favourite. This flash based version of classic Pac-Man game had a good graphics, seamless while operating using keyboard & worked like a charm. But due to copyright issues, it was removed for downloading. The flash exe file is not available for download anymore.
Recently I just saw that Neave Pacman is available here to play online. Neave Pacman has been integrated in their website, so we can play it from the browser. And we can even store high scores though I am not sure for how long they keep the old scores. Anyways if you feel nostalgic & just want to try out this awesome Pacman version again, at least you have an option.
