Looking for good games

Lately I've been playing Miitomo, it's a good app that allows you to interact with your friends through your Miis, but there were missing additions to the application that I would like more. I uninstalled it and started looking for good games on the Play Store (there weren't any). I'm looking for a good game that has old-school graphics or a game that could be just as interactive as Miitomio. Do you know Cube Worlds? Those toys that look like Tamagotchis but interact with each other?... no?... well, I'll leave you a demonstration video:

I'm looking for something like that, a game where you can create characters in closed spaces and as you create more characters, they interact with each other!!! (not like sims)
