I exist (herobrine.ga)

herobrine.ga ("I exist") is a relative to the Herobrine website, with unknown objective. It's most likely that the website is some kind of the Alternative Reality Game. It was first spotted at several minecraft-tagged discord servers, published by I EXIST#1305 user. Immediately after publishing, the user left a server. The website's riddle has not been solved yet, but exploring is still going on.

Description
The main page has a slowly zooming image of the Herobrine itself on the black background and looking at the visitor, under sound accompaniment in form of a variable thuds.

At this point is known that long-stay on the website causes a redirect on the menu page that represents a three strings with different colors with a Herobrine with red glowing eyes on the background.

The first string says "I exist", or "Unremoved", sometimes there are another strings. It's unknown how many are there. The second string contains a link that opens a window "Enter the keyword" with an input field. At this point the keyword is unknown. The third string contains the words "Jafosruf Fanrsomk" with unknown meaning.
