How to play Demon Killer
Nothing here needs explaining twice. The controls are listed in full in the table below — there are only a handful of them. The game is wide rather than tall — fullscreen is worth it on a monitor, and on a phone the picture is much better sideways. Nothing is lost by trying something reckless once.

Why it is worth playing
What makes Demon Killer stick is that failure is informative. You can usually name the mistake, and that is what makes another attempt tempting. It is not trying to be anything larger, and it is better for it.
