An updated version for people who liked the original formula but wanted more. Which makes a lot of sense. It seems to call back to a lot of early platformer games Nintendo put out and that's fine with me. It adds a few things you'd expect, like more jumping forgiveness. The key part bugged me because it's B to pick it up, but you can't move and pick it up at the same time. I literally tried everything except just standing and pressing B. Doh.
