I thought you didn't really want Geno. I don't, but I am not against him anyway for Termina all they have to do is increase the distance between the platforms to make it legal because then fox couldn't use his >B and he would be forced to jump under it like every one else making it fair right?
For Geno's stage thay could actually make it the mine where you first get him and that would make some sense. It could have a roof on it, but you would be able to go on top by going out of the mine and then it could have a mountain above the entrance ( sloped terrain that leke Hyrule where is is textured, but acts the same as a standard slope ) and then it could have another entrance on the other side so you could be killed both way and then lava on the floor with staggered platforms inside so the only way you couldn't be killed is up when your in the mine. Lava equalls water only damages will you are in it so you can fall through it, but if you are forced in it you have a chance to recover, but you take damage as a penelty. It would be a pretty decent size stage, but I think it would be nuetral it wouldn't favor anyone I can think of except maybe the people with five jumps, but that is wher the staggerd platforms com in the make it so even those charcters have to land on the all the platforms to make it across. Ther would only be two or three in the level so as not to make it massive and you could die outside the mine by falling like you fell of a mountain or something if I remember coorectly ther was a sharp dropoff at the entrance that could be the scenary and just make it fatal because you fell to far or something they could make that work I'm sure. What do you think it is just a possible suggestion though.
