I've read here somewhere that there should be 333 total star coins in the game. I've beaten every level with both M & L, with the gold flag, including World 8-Crown. And, AFAIK I got every star coin from the mystery boxes. The only thing I can't say for sure is that I hit all the mystery boxes as soon as they "re-upped" ... I might have played a level or two before noticing that they were active again. But whenever I did the boxes, I never missed getting a coin whether it was new or "old" (i.e. clear). Anyone have an idea why I would still be missing 5? Is there anything I can do about it now?
