Should I buy Terraria to play with my kids?

Ok, so I've been looking at Terraria for a while now and I'm inclined to get it. Nonetheless, since it's to play with my 9 and 11 year-old kids, I'd like some sanity checking, so I've come to the most biased knowledgeable place on Reddit I could find. :)

They're not "difficult game" kind of gamers, they like to collaborate and create things. They do a lot of Creative (and survival) Minecraft, but very casual - they enjoy the exploring and building part of it (not necessarily the "discover new recipe" and "how can I craft X" part though). They like that, if they lose, they just respawn and keep going.

I was hoping that Terraria could satisfy that itch as well - hoping that they are not forced to get into battles unless they want to, or that we can collaborate in that they can explore, gather resources, build and take care of our base, and potentially come on quests/adventures/missions with me for the more action-y/difficult parts.

Is Terraria a good choice in this context? Am I looking at it the wrong way? How are the controls - complex, or mostly movement, mouse and a couple of keys?

Thanks!
