Not the dev, but if you play all of the levels in order you shouldn't have to replay any levels, since it unlocks the next level instantly (in fact, since Ina's and Moona's levels unlock at the same time, the level unlocks should be ahead by 1)
To clarify for you, when I was talking about replaying levels, I was speaking in the context of having played previous versions of the game in the past. Thus in this version, where stages are locked by progression, I was essentially being forced to replay older levels to gain access to the newer levels.
