Thought I'd make a thread for detailing how a skin (not currently in the game) could differ from the original character. I'll just make an example with none other than Giana (over Mario). First obvious difference out of the way; always one tile high. It's already been established that modifiable hitboxes will have to be figured out first, but I wouldn't put it behind them to figure that out. (and yes I know it looks a bit odd, but it's not that bad, really.) Next difference; no run button. This is because Giana Sisters games never had a run button. Now I know you think this will cause a bit of problems in a certain level, but I have a possible workaround for that. Difference three; slightly lower gravity. Really, nothing too noticeable, only just enough so she can make the jump in 8-1 without those stupid helper platforms. And this is more or less an optional difference; fireballs bouncing off walls. That's how it worked with a certain powerup in the original game. Go ahead and make your own for skins you'd like to see in the game.
