Curse of the Sea Rats, the "first Metroidvania starring rats", has been announced for Nintendo Switch. The game has a tentative release window of 2021.

The game is an exploration-focused side-scroller with RPG elements, which focuses on a group of heroes who are transformed into rats by a pirate witch. Players are tasked with helping them rescue the Admiral’s son and breaking the magic spell once and for all.

You can check out some pre-alpha footage of the game in the trailer above (as you can likely tell from the 2021 release window, plenty more hard work will be going into the game behind the scenes before launch), and we've also got a handy feature list for you below:
