For me, the game pretty much ended after the "HOLY CRAP RUN LIKE A BITCH" time-limit thing. That was fun as hell.
The Gloctiki were tough, but I still beat 'em on my first try.
I mean, it's just not a "final" encounter if you don't have to play it more than five times over without dying, which was what the "three minute" level was for me.
And yeah, it would have been cool to do that after Sekto, but then again, Stranger wouldn't get to lift Sekto's corpse up in victory if that were the case, now would he?
