I see that S.N.N. was really trying to get the less experienced/more inferior of us to creep out -- it seemed to work!
I am not the best person at hacking SMW, but I figured I'd give this a shot. I'll never win the contest if I don't try, now, am I?
This is what I figure to be somewhat equivalent to what a ninth door would be. Yes, it does use only 2 colors, and no, I didn't draw a full-fledged title screen or make a huge overworld for it. Ignore everything but the level.
I hope you will enjoy and such.
