Huh. So, basically, that third door that's near the teleporter.
I'll try it out once I'm ready for it... one day. :p
Today: beat the ARC-V campaign of Yu-Gi-Oh! Legacy of the Duelist Link Evolution.
That just leaves VRAINS' campaign to finish. And the reverse duels.
Also got to Chapter... 4, I think? of 7th Dragon 2020.
Then again I got up at like 6:30 AM this morning, haha.
And finished Pokemon OR Delta Episode... but no Deoxys caught. (Kept its HP low as possible, chucking Ultra Balls until it went out of fashion - and stock - and then 1 Timer Ball and... then lost the battle. Loaded a past save state, just to get rid of Deoxys.)
Also: can't start the Looker stuff in Y, so I'm just catching stuff I haven't caught yet.
(Shiny Golett get.)
... I'll probably repost these things in my own gaming thread one day, I dunno. :p
