Created for Ludum Dare 24, Evoland classic became instantly popular and won the competition. There's also a non-free version, but I'm a wee bit poor at the moment so I'll review the free one which can be played here.
I'll admit that this is a pretty old title, but I've never owned an Xbox, so for me this game was never one I could play. Pretty recently though, a friend and I decided to give it a couple of plays.
