These are the requirements for getting the five Stars to appear on your save file, which are needed to unlock the true final level, S8-Crown. Glittering Stars are optional, and makes your stars glitter. Glittering Stars is sometimes known as Rainbow Stars. These cannot be lost if the main game is beaten after obtaining them. Although the second star requirement may seem nearly identical to the first, this is not an error. It's probably there because some levels are optional.
