If you haven't yet tried
Sway, the
game from Illusion Labs and
ReadyFireAim, now's the perfect time to do so. They've released
a free version of the game that limits you to three levels and just two characters, but it's enough to try out the really unique control scheme. Back when I first posted about the game, I hadn't tried it yet, but it's now been on my iPhone for about a month, and it's excellent. Each of your thumbs is a "hand" on your characters (i.e., to grab something with your left hand, in game, you just touch your thumb to the left side of the screen), and then once you've grabbed something, you can swipe that thumb back and forth to sway the character around. It gets pretty complex, but practice makes perfect, and a few stages in, you'll be swinging from grip to grip with the greatest of ease.
The full version still costs $4.99, and if you enjoy the free version, I highly recommend it: there are many more characters that you can pick up and choose from, and the stages actually get really tough, as there's a lot of precise swinging that you'll have to do to explore the whole area and find everything there is to find.
Sway might be a sleeper hit for the iPhone -- it took me a little while to figure it all out, but once I did, I found a control scheme that's delightfully original. If you haven't tried it out yet, definitely take advantage of the free version.
