EscapeSlide! in liminal spaces

Like that Q.M., it's lying on the floor of the dreamcore of yours, or someone else's.( We can't rule out the possibility ,that you are you and you are not you.Following Intuitionists.)
Anyway, have fun! In second stage, mysterious rooms and some puzzles will amuse you.
Finally you can see that cute oriental cat on the floor where you may experience wonderful but confusing "Gimmicky" World.
We look forward to having you join us!

(from "Hamlet")
Ber. Who's there?
Fran. Nay, answer me: stand, and unfold yourself.

From the beginning, the person who should be asked is asking the question.
In a sense, our world is upside down, isn't it?
Anyway, the fact is lying in this phrase: ex falso quodlibet.
