So, yeah, as mentioned it’s pretty similar to Murder Mystery, though I understand where you’re coming from with slight differences. However, we have a game on Java called Trouble in Mineville, which is very similar to Among Us, minus the tasks. When we added Murder to Java, it all but died because the two games were similar enough that the community got quite split.
We would be unlikely to add an Among Us-style game for the same reason we never added Trouble in Mineville to Bedrock - Having two games on the server that are so similar causes a divide in which one people want to play. So, sadly, we’re very unlikely to add this.
