I have idea for 2 new category.
First one is CHAOS mode.
And the second one is all 3 fun settings
the first one already exists, and you can find it in category extensions
and the second one is complicated, you see, the "lights out" and "mirror mode" settings don't change the gameplay at all, it's just visual, (and in fact, tuo_telly, one of the best players of this game, uses the "lights out" mode for his runs, because he can locate the Principal of the Thing better using that mode)
and since it is only visual, I don't think it is considered important enough to have its own category, so, instead, only "Hard Mode" has its own category in the category extensions, since it is the only fun setting that changes the gameplay.
and that's all
I often use lights out mode too because principal is a menace at reaction times.
