well i just found this bug at a server, it is version 3.30 so i dont know that it is fixed or not. when u choose the char and enter the stage,u can do nothing except when u attack there will be the air attack sprite then gone.
i dont know what happend so i just report it. if its fixed then im sorry about this post. Thanks
As Kai Kuro said, Snow Stage has been removed, and I doubt I'll add it anytime soon. It was a really useless stage, and people hated it, I'll try to add new stages, but the chances of seeing snow stage readded are very very few.
