This may be a really stupid question, but is there any way to restart a level from the beginning without starting the whole set of levels over again? The only way I've seen to do that is to exit through the entrance of the level, but that isn't always possible.
I remember answering all 4 riddles (I've gone back to each Riddler and checked twice) but the game says I've only answered 3... which means no badge for me. Is anyone else having this problem? If not, maybe I just did something wrong! Any advice?
