Can we make the game before 7 PM and then upload it at 7 PM? IDK If I will have any free time in the 24 hours gap. Of course we will record all to show we did it in 7 minutes.

You can make it at any time during the day as long as it is in the 7 minute time limit.

Oh wait sorry, ok, yes. You can make it the day before if necessary, however, it would be preferred if you would do it on the day it starts.
