Which are the proper #Hastags for promoting independant games made on the CORE platform?

Which are the proper #Hastags for promoting CORE applications / games of us, independant developers on the CORE platform?

I found by Google, especially on Twitter & YouTube:

General:

  1. #GameDev #IndieGameDev #IndieGameDeveloper #IndieDev
  2. #kitbash #kitbashing

Special:
3) #MadeWithCore #CreatedWithCore #MadeinCore
4) #CoreGames #ManticoreGames
5) @CoreGames
6) #UnrealEngine

Questions & comments about
3) No question, I think that are my best choices. But which is the officially suggested one?
4) Is this ok, if I am just an independant game developer?
5) Is @CoreGames ok, if I am just an independant game developer? Or is it just ok to be used by Manticore and Manticore staff members?
6) is this helpful & useful for CORE games by independant game developers, to indicate that the game performance is built on the UnrealEngine?

Sincerely
Rolf
