It looks a bit more freeform than Episode 1, but nowhere near as much as the classics if you ask me. A particular level near the end looks a bit linear as there are dash pads everywhere that keep you travelling along mostly at the same speed, but it still manages to seem better than the previous attempt. As I haven't played it, I can't really comment - but from the looks of it, it doesn't look like a game that's going to have the same kind of replay value that the classic games had. Secrets, though? I'm sure there's going to be a few, I haven't really noticed any but then, I've only really watched the levels once each on YouTube and the people playing weren't discovering any.
