Was dusk made in Unity?

Excuse me, could you clarify something for me? I've come across some information that mentions "dusk" being developed or made in Unity. Now, I'm not entirely sure what context this is referring to, as "dusk" could mean various things. But assuming we're talking about a game, software, or perhaps even a blockchain-related project, could you confirm if "dusk" was indeed created or developed using the Unity platform? I'm just curious about the technical aspects behind it and how the Unity engine might have contributed to its creation.
