We like Oceanhorn here at Pocket Gamer's island paradise. Sure, it might stick a little too closely to its inspiration, but when that inspiration is Zelda, you can't really complain too much. We didn't, and gave the game a Silver Award at review.
But if you're still undecided as to whether the game is worth an investment, FDG Entertainment has released a free benchmarking version for you to try out.
It's essentially a demo of the first chapter, and it also tells you how well the game will run on your device.
You can grab it from the App Store right now for nothing [download] and see if we were right to call Oceanhorn "beautiful, adventurous, lengthy, and a strong stand-in for The Legend of Zelda on iOS."
