Yes, the number of levels has already been addressed; I don't know every single detail of every single level, but it is intentional that all of them are remixes of Marble Blast Gold levels with only small changes from the original, and sometimes remixes of earlier levels I made (like level 53 is just a harder version of level 32, for example, but this is valid because in the original Marble Blast Gold, Intermediate level 23 was nothing more than a harder version of Intermediate level 2 with the only change being the pit stop, more gems and powerups, and different gold times and qualify times, or also Beginner level 18 was nothing more than a harder Beginner 16, or also Advanced 19 was nothing more than a harder Advanced 9, and so on).
