So after I beat a level on SSE the dot on the map will sometimes have a green flag or sometimes it will have a flashing multi coloured dot. When I go back to replay the ones that are color flashing dots it gives me an option to play it ona hard difficulty which I do. Amidoinitrite? What's the signifigance? Anyone know? edit: so it seems the green flags mean the level still has items I didn't get? Not sure how little of an item warrants a green flag though.
