My wife and I LOVED playing Limbo, together. Well, to be more accurately, she loved screaming directions at me in panic as I died to various nasties ;P

I won't spoil anything about the game—it seems like you're only partway through—but I've found the more recent platformers being released have been exceptionally charming. Most have a subtle narrative, an eye-catching visual aesthetic, and some gimmick that's fun to engage with. In this case, the B&W color scheme is outside the norm enough to add intrigue.

Hope you're enjoying the game as much as I did!
