So far I am loving Cahaya. I have mainly been playing on the main island, as I am enjoy the farming aspect of the island; but, I have explored the resort island a little.
For both the resort island and the main island, I think if there were culinary dishes that were exclusive and specific only to Cahaya would be great - main meals, deserts and drinks that give off an island vibe. As it would really give the resort side of Cahaya a vacation, getaway vibe.
Regarding the farming aspect introduced with Cahaya, I don’t know if you can farm in the other worlds in InZoi, but if you can, then I think also introducing produce that you can only grow/ obtain seeds if you go to Cahaya. Whether that be going to Cahaya on holiday or moving your household to the island.
Also, surfling. There are surf boards around but apart from practicing with them on the beach, you can’t actually surf with them. So introducing surfing, and a surfing skill would be cool - which could also incorporate owning or working at a board shop, and Zoi’s being able to purchase a board, but also possibly being able to make a surf board, and deal with the general upkeep of a surf board. You also have snorkelling already, but building on that and also perhaps incorporating deep sea scuba diving spots.
Loving it so far, though. Keep up the amazing work.
