There is an ARG in BurningKnight/Content/Readme.txt

I'll get to it, SOON!

As of now I am stuck in the "Just read the instructions" pointer and am currently too lazy to search for clues elsewhere, so if anyone wants to continue after me here is what I did:

1. Go to bitly link located in BurningKnight/Content/Readme.txt
2. Decoding the base64 gives you "Limpor's diary" and "https://rexcellentgames.com/ld/"
3. Going to the link you have to enter the password found in the bitly link page source O7ZgmQrBHHi$03oYbg#pwa
4. Clicking the burning man link at the bottom of the page gives you an mp3 file. Running it through a spectrogram gave me nothing (correct me if I missed smth). Checking the hex dump of the mp3 gave me the following link: https://rexcellentgames.com/ld/prophecy.png
5. Again reading the hex dump gives the text "Just read the instructions"

Hope this is enough to continue after me. Good luck.

Got close, the final piece is in the image itself, should be pretty easy to figure out, didn't use anything "smart" or "out of ordinary" to be honest, made this over 2 years ago, could've been more creative now.

That's cool, how did you manipulate the image to get that? I tried brightness, contrast but those didn't work.

index image, then change 1 of 2 colors

Or bump contrast, yeah
