How did you unlock the master quest map and the great sea map? I've beaten the normal map but I've gotten zip from it.
Each map has a 'final battle' level which ends with a cutscene and unlocks the next map, I didn't need to beat all the levels in a map to unlock the next one.
You've said you beaten the normal map so the Great Sea Map should be unlocked now unless you maybe missed that one level (I'll try and add screenshots showing which levels they were later). I had also beaten the story mode if that somehow is relevant.
