I noticed something strange. I got 6 emeralds on my first run. I was greeted by a screen that told me I could grab the last one by way of level select. So, of course, I tried it out on one of the earlier levels to grab it and go and it took me to the first special stage for some reason. I beat that, and the usual emerald collection on screen wasn't there. When I tried on the next level, it just took me to the same special stage with the same result. So I just decided to man up and replay the whole game. Emeralds collected just fine through the "Game Start" mode, but I tried it out in level select again just to see what would happen and the special rings wouldn't even appear. Seems to be something fishy going on with the way the game saves or something. Wonderful game you guys have here, despite these minor glitches and flaws.
