“Decade is a narrative point-and-click adventure game where you will send children back into the past - ten years at a time - to learn how the world ended, and what you can do to change it,”

RPS: "Decade is a tech-noir adventure game where you send children back in time to prevent metal rain from pulping the planet"

Disco Elysium - one of my most memorable gaming experiences. I don't know what Decade will play like but it may not feature any walking at all. Not sure where you've gotten that impression from. Sure doesn't look like it'll be in a similar mold as Firewatch, Gone Home, What Remains of Edith Finch or any traditional adventure whatsoever. I personally quite like those too though.
