One last "???" item?

[Stepper of the Long Earth]

Alright, I have got all 49 cards. All 13 Secrets (And 14 with the golden broom). And all 6 achievements. Now, why oh why, is there a blank space that you can select in the "???" menu? It only shows up AFTER you beat Briar for the first time. (I checked with the "give everything cheat code on a separate file.)

I am assuming this is a bug but I can never tell with this game.

Okay.... that's not quite true. After I beat him, it does allow me to select the blank one. It only pops up with "(A) : Select" which is more that what it was doing in the base game. Which was nothing. Sooooo, maybe it's an invisible ??? item that's collected in some obscure way?

Alright, after some testing, when you first boot up the game, enter in the "get everything" code (UUDDLRLR21) it does not appear. If you go and then quit to the menu. Start up that game again, it appears. enter the code AGAIN will get you the (A) : Select prompt. I have no idea what to make of this.*

Fun fact: If you erase an old game. And then immediately start a new one (or open an old save file, then quit to the menu and start a brand new game) the timer remains the same? Yeah, it was kind of a surprise when I started a new game and realized that there was already 20 minutes on the file...somehow.

*It's definitely not the 'beat the game in x minuets' thing hinted at by the devs.
So ¯\_(ツ)_/¯

There *is* a final card that is only possible to get with a lot of trickery. You're not really supposed to get it; assuming you played through the entire game it should become obvious why
