The Henry Stickmin universe (hsu) and the Among Us universe (auu) have a lot of similarities. In Completing the Mission, one the bios is about a guy who won a contest to name a planet after them who's last name is Polus. From the airship map trailer, the airship has a decal that shows a crewmate, unlike in Infiltrating the Airship where there was no crewmate decal.
That's all the evidence I have found so far.
But hey, that's just a theory, a game theory.
