Full of challenging combat and puzzles. But alas, Rainbow Sea is devoid of both. There’s no inventory, no weapons, and no challenge. All you do is wander the ship and chat with the gods.

They basically just involve your character automatically completing a task or answering questions. You can learn the requirements of each event by watching an ad. Since there are hundreds of events, it will take a while to unlock the conditions for each one. Rival Megagun Switch NSP
