Easy Question?

If you hit suddenly slowed before hitting the wall, Nene would assume it hit the wall and did not fire a bullet. Allowing you to get away with a free shot.

But I remind you that slamming into the wall may lower your own score (if you mess up). It also gives a huge and useful data spike and stops your robot. Which means may not work against the top bots very well. Since they are made to capitalize on that.
