It's the sophistication of the narrative and language, I think, with some darkness to it, which stood out to me in both games and made me mentally match them. I don't see too many game jam games where the player is temporally shifted for portions of the narrative. The style of game, sci-fi/space setting, pixel art style, and the reference to a sun-god right near the start -- those probably also prompted me to think of the Gnawing Hunger. Other aspects differed, but those were the ones that made me look to see if you made both.
