Looking for a surreal comic I once saw posted somewhere Spanish

Hi! This was an existencial and surreal comic of a character that descends down a mole like tunnel, finding different characters in the ways, and having to choose different paths, and in the end it finds an anglerfish like character that tells the main character that any atempt to return is futile.

It was drawn in black and white, almost without shading, and pictured by the side.

Does it ring any bell?
