I did see the game restart, and saw the "Later..." message, and I guess it does say "THE END" and "Thanks for playing", but I couldn't quite remember if that's also what it said when I died =). I thought it might be the end, but since it felt like it was half way through a level, I wasn't quite sure... had it been right at the beginning / after going down the stairs, or a clear end of level dead end, maybe it would have been clearer =).
