After leaving Sega, Yuji Naka’s studio Prope made the innovative Wii game Let’s Tap. These days, Prope is mostly working on developing Digimon games for Bandai Namco, but they occasionally release a wacky game for smartphones like E-anbai (or Just Right in English).
In E-anbai, players turn hot and cold water faucets until the water temperature is just right for guests. If guests are happy you’ll get more visitors and you can spruce up your bathhouse with fancy faucets and Manneken Pis. The game also keeps track of patrons and you can see how often dudes stop by. Not all the customers are men though, ghosts and dragons also show up bathing alongside regular people.
