I remember triying it a few years ago when the online version was released. The problem is that a lot of modern shorcuts are mising, like click on an enemy unit to atack instead of pressing A and then clicking on it. It was fantastic when it was released. Perhaps someone can add all those small tweaks and make an updated version.
Was going to stroll down memory lane, and play it on a retro website. Sadly, Firefox is broken in this regard (what a shocker), with a broken UI that maps escape to 'exit pointer lock' or 'exit fullscreen'. Esc is used to bypass mega-long intros, and scenes between play, and other things of course.
There's no way to change the esc key to another key, which is just silly. Which makes Firefox silly.
