Superbrothers: Swords and Sworcery EP
It's difficult to describe Capybara Games' Swords and Sworcery. One part adventure game, one part amazing soundtrack, I often found myself just sitting there listening to the music rather than actually playing the game. Once you're done being mesmerized by the awesome music, you'll be poking around the 8-bit landscape, looking for the right path to take or the puzzle to solve that will allow you to continue in your adventure. The game is short, but Swords and Sworcercy is a must have for any iPad owner.
Forget Angry Birds and Cut the Rope, Triple Town by Spry Fox is the new hotness when it comes to casual games. The premise couldn't be more simple. You build a town by matching three similar objects. Once matched, those objects merge into a new item and you get points. While the items that are created don't make very much sense (how do three trees become a house?), the challenge comes from having to deal with the bears (and ninja bears) that get in the way of your matchmaking. Triple Town is the perfect example of a game that is easy to learn but difficult to master.
