If anyone figures out that secret in this update, let me know... I have tried everything and I can't figure it out. And once you do, put it on the wiki too lol

ALLEGEDLY, (I haven't been able to get it to work on Mac and if this method is accurate no clue how it'd translate on android) it's the Konami code per this tweet (https://twitter.com/RandomVNGamer/status/1781083196471349463).
AKA, Up, Up, Down, Down, Left, Right, Left, Right, B, A (With the tweet claiming that it worked using the numpad subbing B & A with 1 & 3 respectively making for the input being 8 8 2 2 4 6 4 6 1 3). I tried both variants (directional arrows + B A and numpad notation) and it didn't work for me maybe because I'm on a laptop without a numpad? Idk. But if others can get it to work and someone could record it, that'd be good enough for me.
