Well the obvious one would be checkpoints.Checkpoints would not only make longer levels more viable, but also would make other items more useful, like the 1-up.
But the one i want most is the possibility to make your own custom boss battle, like for example when you batttle him you enter in a separate room, and when you defeat him you finish the level, and also be able to customize his atacks(every 3 second he launches a green shell for example)That would be truly awesome
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
