No idea if this has been already suggested or even implemented before, but fix thok attack trailing! This issue was there always and never fixed: the trail only appears for the first frame. This is because the thok is only one-frame long, the rest is handled by the normal engine. I think I know how to fix this. Some flag probably is activated to prevent the player from multi-thoking, right? Well, that flag could also be used to make the game to add trailing, too. Of course, touching the floor or anything that would stop the thok would also stop the trailing.
Would that work?
