I understand, from a scoring standpoint, why it doesn't...but I feel like if I have the opponent locked in to the point where they cannot possibly come back, it should just call the game in my favour.
Tip: Move as little as absolutely possible. Just stand in the middle of the screen and try to keep an eye on the edges and the top right around your area. When I got it (took a dozen or so tries), I moved probably less than an inch total and jumped only once.
Do the motorcycles KNOW they've finished a lap, or are they approaching it as one continuous course that's thrice as long as we see it? That would explain part of why they remake the same mistakes on a second lap instead of going "Right, I'll just do that again since it worked last lap."
