This is what I like to see! Developers doing really interesting things with the Switch, just like several studios did with the Wii U (Rest in Peace).
Evidently the Japanese developer Gift Ten Industry is creating a project that's codenamed Madolica, and will arrive in Japan for 1,500 yen in an eShop-only format on Switch. The gist? You'll need to escape an evil mansion in-game, with the help of real life-printed maps from the game's official site. It supports up to four players, and naturally, you can take it to a game night along with the maps on the go, as it's built to focus on portable play.
As someone who has regular tabletop nights, I'd immediately give this a shot, especially for roughly $15. There's no word on a localization yet, but it might be possible to "import" it on the eShop and play it worldwide if it doesn't require too much knowledge of Japanese.
