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.
