sudden death is nearly impossible, runes give you 0% boosts (how useful!), there is a mode where you watch your idiot ally fight, and you unfortunately can't switch character. I like how the assassin's name is Desmond though
Use whatever graphic program (or can use Pencyl program inside of Stencyl) and find the resize options. For example, in Paint.NET, on the top, I hit Image -> Resize. Be sure to take a look at the collision size when uploading a new image since it doesn't always scale to the new size (so your graphic might be smaller but the collision box might be still the same size).
