thanks for correcting me, i also put an entire playthrough in a spectrogram and found nothing. and that string of numbers but with the 5 very well could be a url link. ill try it out, ill tell u if i find anything. edit: i havent found anything new, do you think it might have something to do with the safe code ingame?
I highly doubt, that the developer went so far with arg on his first game demo, but I can try to do some reverse engineering ; luckily I have some C# knowledge and the game was made in Unity. I've never have tried to get the source code of any game before, but I'll let you know if I find anything interesting.
P.S let's chat further on discord, if you have any. Here's my name : azaza#4459
