Like some have said, I think these death traps only work best on a 3D plane. You can get around it much easier. So it wouldn't really work on a 2D plane.
Although on a side note (and a bit off topic), I would like to see stage extensions in MK9. Not with just an uppercut either, but maybe 3 neutral jump punches through the ground? Think about it.
Like UMK3?![]()
