This game has a lot of issues. A lot of issues. The blue coins especially as well as some of the horribly designed shines like pachinko and the poison river. However, that doesn't really matter, because everything else about this game is fantastic. By far the best movement in any Mario game ever, the most lively and fun world, a great soundtrack, it's just amazing. Also, pretty much none of the bad levels are required to beat the game, only to complete it.
