This game is freeware. Although ending screen says otherwise,
it is. The reason ending screen still exists is that sources are somewhat
corrupt, and I am unable to build new version of game using them without
too much work.
If you can't tolerate blood and/or violence in any form, we highly suggest
that you delete this game now, if not sooner. Also, if you think that
computer violence and evil marks can make you an satanist or maniac or
anything like that, you should not play this game.
