well, at the moment for everytime you teleport it leaves behind an after image. Imo the first time you teleport when you teleport more than once in a certain time frame, thats where you should leave your only after image, after than every other teleport until you stop teleporting for more than 1 second or something (rough guess) should leave 1.1 style effects(improved though) like speed lines making it harder to see the oponent.
watcha think?
