A lot of these aren't cheating, just being good at. For example, at Where Goes The Nose, 5-volt is not cheating because she has no way to super easily get the right nose every time, she can just easily GET it if she knows which one it is.
Most of these she doesn’t really cheese, with some of them becoming harder because of time. The ones she cheeses are the ones where you need to get an item or leave an area, where the challenge is getting there in time.
Notice how the cage (Hide and Go Ninja) and the glass (the Food Looking micro-games) prevent 5-volt to use her teleportation? They should give an element restriction (nightmare wave) that prevent 5-volt to teleport. If it is the intended way by the developer to win as 5-volt, I don't see the complain. 16:58 Oh, how new.
It’s been explained in GOLD that 5-Volt’s husband is a firefighter. That would explain the helmet that 9-Volt wears. It looks like a modified firefighter’s helmet.
