Hi @tht, regarding question 4, you must describe and document with screenshots the process you go through to acquire your tokens and to connect your wallet to the game, however, it is not necessary to describe the whole process of downloading and installation beforehand.

If the amount of SP you have in your account exceeds the minimum required (400 SP), before and after the PowerDown, you should not have problems to participate, however, doing Power Down is not recommended, I suggest, if it is in your possibilities, to stop it.

I look forward to your participation.
