I actually spent a lot of time thinking about this. While I understand your frustration, I believe it's related to a mayor problem that videogames as a genre are facing today: there is clearly a breach between two different conceptions of videogames.
What you're asking for, probably, won't be easily found on Itch.io, a community for people that abide to different ideas of what a videogame should be.
That being said, a game, in it's most traditional sense, has some clear characteristics down to it's core: rules, a condition of winning, and one of losing. (in between, and particularly, in videogames, you could think of gameplay, graphics, etc).
The main issue, I think, is that we are using the same word for two very different things. The Things We Lost in The Flood, as most games on Itch, is meant to be highly discursive, and that is reflected on all of it's aspects. You are asking for a different kind of media; one, that, sadly, is understandably linked to the one that is mostly featured here. My hope for the future is that these aspiring new media shall be analized for what it is, and not for what it "should" be, given that, obviously, it's roots are buried in the notion of traditional "videogames" (and, more importantly, "games").
