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

I don't mean to answer for him but the snow stage was removed until he may fix it or he will never add it again. But that doesn't sound right.

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.
