Anyone can break stuff, but Icebreaker: A Viking Voyage requires you to break things with precision. See, your Viking comrades have been swept away in a storm and frozen in ice, so you've got the bust 'em out with a hammer. That's just how Vikings do.
Icebreaker is another physics puzzler, but it has a fresh approach to the genre. You have to slice icebergs, ropes, and other objects to collect your friends from around the level. That might require making just the right cut so they slide into your boat, but other times you'll have to shoot them out of a cannon or knock them off a ledge with an ice boulder. Yeah, there's some fun game mechanics in this one.
The graphics are cute, and level design is very clever in Icebreaker: A Viking Voyage. For $0.99 you get 140+ levels with boss battles, quests, and so on. There are some optional in-app purchases, but they don't seem to be pushed too hard. It's on a 50% off sale to celebrate the launch, so act quick to save a buck.
