My non-gamer newlywed wife loves It Takes Two. What else can we play together?

I got It Takes Two with the summer sale and even ordered a pink controller for her to use. She loves playing together and I'd like to keep this going.

Any recommendations on other games I could get for us? It needs to be split screen compatible since we just moved to Japan and don't plan on owning a TV or another PC anytime soon. Thanks!
