How many levels in this game?

Would someone please let me know how many levels are in this game, and are there any bonus levels at the end. Thanks a bunch!

I am not finished with game yet, but there are at least 63 levels (the statues in the valley each have 16 pieces to carve out for each region)....not sure about any bonus levels.

64 levels, I guess. (There are 192 coins)
