No problem, here are some tips! It's easiest if you turn on the hints in the Options menu too. ;)
For Sea #3, try lowering affection with Malik, but choose to get to know him better at the party.
For Sea #4, try building your evil karma. Raise Mikali's affection higher than Malik's, but choose to get to know Malik better at the party.
For Land #4, try lowering your affection with the sorcerer, but still return to the island.
Glad to hear you're looking forward to the full game! We haven't chosen the release date yet, but will but sure to announce it when we do.
