I have a question about Mario Circuit. From videos I've seen, it looks like, when you're on the bottom, you can't get KO'd/KO to the side, and the jump in the course makes kind of a box that traps people in. So, from what I've seen, the only way to KO is off the top from the platform in the middle, but beneath the ramp, or when you're fighting on the ramps on the side, which look kinda awkward to fight on.
Also, if the course does make a boxlike thing, it would be infinite-jabable, unless if you can get hit by one of the racers whilst doing it.
But then again, I could be completely wrong about EVERYTHING on this stage, and it could be completely fair. Could anyone clarify these things about this stage?
