The new animated character sprites look great, and the menu design is superb as I expected! I always enjoy all of the subtle visual effects in your games, like the moving portrait silhouettes, character transitions and the reflections on the title screen in this one. They just make the presentation feel polished and deliberate.
There's a good amount of descriptive writing, it's neat that there are so many world elements to check out in different ways. It's also cool to see the story branch out into three routes at the end with their own flavor text. The overall narrative felt somewhat leading at times with a few of the major plot hooks introduced a little abruptly.
Music selection is excellent, the tracks capture the tropical island theme perfectly. There's a good variety of sound effects for the screen transitions and notifications. Most of the time you're taking and interacting, so perhaps there can be some sounds for the more common action the player performs?
This is a big game to finish in a month, and it feels very complete! Excellent work!
