Berka probably took it down a few times to fix things and you know how ratings/finished stats don't line up sometimes when that happens.
EDIT: I guess you could add a suicide choice, the only downside I suppose with that is you'll potentially get people rating it a 1 because they couldn't finish it.
Just checked and see that I successfully completed it in 2013. I seem to recall that his moustache is all powerful.
KAM is actually my second favorite storygame on the site. I did spend a great deal of time on it (such as being stuck over an hour on the fake end game link). Nonetheless, it was a brutality that was highly enjoyable. If there was an early (and real) end game link, I'm afraid my lazy self may have taken the easy way out thus robbing me of the rest of your great story.
I definitely enjoyed it, I'll try it again later when I have more time. Also, maybe Briar_Rose would have more time to finish the sequel to her featured story if she stopped trying to murder me while finding this mustache.
Also that statistic at the top may not count for people who finished the game, but closed out without rating it.
