Although it was Japanese only before, one of the most out-of-nowhere eShop hits has had localized text added.
Known either as "Watermelon Game" or "Suika Game", the mind-blowingly popular streaming smash is now available with English support following its surprise North American launch last Friday. A seasonal (Halloween) theme was also added.
Since its Friday launch, the surprise Japanese hit has ranked alongside Super Mario Bros. Wonder in the eShop's top sellers.
