Well, now that I've finished it (once) I might as well share it. Iji is an Action/Adventure side scroller with RPG elements (similar to the leveling up system in Fallout 3 without as many options). It also gives the player options, the big one being whethere you kill the enemies around you or not kill any of them at all (it is possible to beat the game without killing anyone)...so it has quite a bit of replayability. It also has a good number of secrets to uncover.
I love this game. I haven't found myself genuinely enjoying a game this much since I first played through Portal. The story and writting are very good in my opinion and the weapons...oh how I love the weapons. I was also greatly pleased with the ammount of depth in the game. Oh and did I mention that I love the weapons?
