The official Umihara Kawase Fresh! Japanese website has updated with a slew of new content, including the trailer above. The latest batch of content takes a look at the “Mid-Layer” world in the game, which can be accessed using "Lench’s elevator," Lench being a character in the game. Campers frequent this area, and it seems there's something going on with the area that hasn't yet been revealed.
The official website has also been updated with a ton of new screens and art. There's even some goodies you can print out at home! Check out all the updated content here.
