If you haven't seen Papo & Yo's endearing announcement trailer, you should probably go check that out right now. Go ahead, I'll wait. All set? Great. Now that you've seen it, you'll understand why it was one of the few E3 2011 games that I made a specific point of going to play, just for me.

Papo & Yo is a story-driven puzzle game about a boy named Quico who lives in a Brazilian favela, and his two best friends: a quirky robot named Lula and a rhino-like creature named Monster. Lula, unfortunately, scares the hell out of Monster, rendering him too petrified to move when she's nearby.

Monster, on the other hand, is an adorable, friendly giant. That is, until he eats a frog (he's addicted to 'em!), totally flips out and tries to kill everything. I didn't see that part, though -- the demo actually ended with Monster gobbling a frog and a fade to black. What I played, rather, was all about puzzle solving.
