It's VERY glitchy. Press Z to punch, space to jump, left and right to turn, and up to move. It uses an altitude system to judge whether you're above the platform, even if your Y position is higher from jumping. So, try this: walk up to the upper edge and see what happens. It also works with the other edges as well. DOWNLOAD AND RUN IN PRESENTATION MODE! Unless you want endless glitches. This is a game I MIGHT make. As far as I know, it will be the first 3D Super Smash Bros. project on Scratch, but it'll be a pain to implement all of the menus and damage meters and stuff like that. And as you all probably know from experience, 2-player games take forever to make because you have to duplicate every single variable and switch them around in the scripts. Right now it's very hard to program because of the vague collection of blocks Scratch has, and I don't have much time for Scratch these days anyway, so I might wait until Scratch 2.0 comes out.
