Unclear challenge; Winning as many microgames as possible? What do you mean with that? Win 15 microgames? Win the game? Win the boss game? I can't tell what you're trying to say with this. Furthermore, the challenge since incredibly boring. At least in "Get 0 points in a game of Minerware" you can AFK, in this one you can't because you "Have to win as many microgames as possible".
Besides, I can only think of very few microgames where you could win without moving, or moving around as you said. Those would be: avoid the hot potato, TNT tag, stand still on X color, and Keep running fast. Winning four games wherein almost all of them you're gonna get killed by the others and/or are randomly based sounds rather impossible or extremely hard. It's a no from me.
