I've put a lot of work into making sure world 2 feels more full from the start - Something I had to do later on in world 1.
World 2 is composed of three basic areas: A beach town, the ocean and a sunken ship. Today, I finished up most of the preliminary work on the beach town, and started creating the ocean and the physics that will apply to Hue once she's underwater.
Most of what you see in the town will be flavour text, nothing crucial to the game. However, the shark that offers guided tours of the area will help you get a couple of All World Gems in the area, assuming you help him first.
As always, there's going to be a lot of updates to the visuals before it launches, but you've gotta start somewhere, right? Next steps will be making the shark missions playable, and building the ocean portion of the map.
