EDGE: "Trial and error doesn’t sit well with everyone, of course, but it undoubtedly helps that failure offers its own rewards: Mittens getting burned, zapped, crushed or simply yelping as he plummets to his doom is amusing, and perseverance is rewarded with an adorable animation and an instant earworm of a celebratory jingle. It’s formulaic, then, but sticking with what you know doesn’t often produce such satisfying results."
IGN:Though many of Mittens’ levels feature a neat variety of traps and mechanisms, on the mandatory normal difficulty most unfold at a snail’s pace and are simply too easy. Dying is uncommon, and some levels are so simple you might complete them entirely by accident. Mittens shines brightest when it throws you into a dangerous, dynamic stage and forces you to claw your way to the end, which disappointingly is too rare until you unlock the tough levels.

"It’s the age-old love story. Cat falls in love with cat, by collecting diamonds, balloons and milk to win her over. Mittens is the latest game in a long series of physic-based titles on touchscreen devices."
Mittens is a pretty steady offering. The bulk of the game is mostly easy levels for younger kids, while there are some sneakily difficult levels here and there that will surprise you with how tough they can be.
