Hey Cursed File! That was initially added as a little easter egg for the programmers. We weren't expecting our little game jam entry to get the attention it's been getting, so we're reworking that along with other general improvements for the next patch!
Check out the tattoo on Patient #3 to help you out with that "something" on your terminal. From there, try a new run of the game and pay attention to the red text in the files! Smiling isn't the only way to go ;)
When submitting your files, what you do on the terminal will help you not get marked incorrectly. Hope that helps!
