In the second and third day, there's a glitch (which, as I type this, I am unsure if it was intentional?) where, when entering or leaving the basement, you can go outside the boundary lines.

^^ this one can happen on day 2 and 3 by entering the basement, leaving, and moving left

^^ this one can only happen on the third day, and you can do it by entering the basement, and then going up, and you have the whole thing just outside the barrier lines to yourself. It also lets you go down the wall if you move down above the clock or calender.

So yeah !! If you weren't aware, now you are, and if this was intentional, it has been recognised!
