Blade Of Betrayal [+HD] - FREE
Here's the iTunes link for the HD version -
Blade Of Betrayal was the very first platformer that I bought back when I got my first 2nd Gen iPod. It's a nice little actiony platformer with some pretty big levels later on in the game. Unfortunately, it's not widescreen supported as the last update was back in 2010... but it's definitely worth checking out if the deadzones don't bother you, you have an older iDevice or have an iPad.
I haven't played it in about a year (maybe more), but it does open and start up on iOS 7.0.4
