I like it ! I wasn't sure at first if I would keep being confused, but it slowly set in. The prose was a good balance of puzzling references to things you don't know and explaining the setting. And I got one of those moments where the dialogue and music line up and you get a lil chill. Pretty awesome for such a short project, and I'd def play a longer 8bit exploration horror game about sun-madness.
I would love to see the sun on the screen somehow, at the end. Or in a longer game, like out a window or something, as a constant, silent companion. I think the suggestion of the sun worked here for a prologue. It left me ready to go back into that setting and find out what's going on/linger in that ambience more, so I think that's a success!
