It's not often that a freeware game can truly be called a masterpiece but Daniel Remar has finally released Iji, an action platformer with touches of RPG, in which you control a female heroine with a whole lot of engineered superhuman abilities. What makes this game so good is the sheer of polish that has been put into the production and the large amount of choices there are to make. You can choose what abilities to level up with, whether or not to bother killing enemies and the path you take through each sprawling area, which can effect the outcome of the unfolding story.
