Get a great adventure game free for a limited time.
If you're up for a fast, colourful, perky action-packed platformer then the aptly named Swordigo swings hard and fast on iOS devices. It's heavily doused in Zelda-like fantasy and has an undercurrent of RPG mechanics to boot. It's been a resident of this gamer's iPad desktop for the best part of a year, and right now you can check it out for yourself for free.
You can grab the game here. You can also check out developer Touch Foo's second title, Soosiz.
