Garrage

I doubt I won the intended way... I just

did some boogie bot to get to the side with the ball, pushed it into the mass of zapbots, waited for most of them to leave, then jumped off the stairs, hit the ball a bit, got zapped, and the ball rolled to the button.

Probably not at all what you intended?

I push all Z bot into hole

turned out,
we need at least one zapper
to help kill B then slide into winblock hole

@EL797
big pusher in the room is to push all Z
