Are there Undertale in German?

Unfortunately, my English is not exactly the yellow of the egg, but I wanted to catch up on this game because it is so popular.

So I wanted to ask whether you can select German in the language menu (if it is available), or whether there's another option to play Undertale in German on the Nintendo Switch version.

I think so. If not you have to patch it down

Officially there's no German.

There's one for the PC version - but you can't modify the Switch version like this
