Digital release was originally set for sometime this month
May is closer to being over than not, and yet there's no sign of the planned release of the Today's Menu for the Emiya Family Switch game. Aniplex previously had the cooking adventure—based on TAa's Fate spin-off parody manga and the anime adaptation—lined up for sometime this month, but COVID-19 complications have delayed it to an undetermined release window.
The most recent trailer for the game—which will be released digitally via Nintendo's eShop—made its way online back in March.
