A true classic. If you see it, buy it.
The gameplay is very unique. You don't just go right while you kill enemies to reach the end of the level. Instead, You actually use a magic ring of sorts that you use to grab enemies to use in completing puzzles and platforming segments. Many enemies will have different uses when you grab them, usually because this game is heavily puzzle infused. Everything is very fun and fuses together real nice. I give the gameplay an 8/10.
The graphics, although not the best from a technical stand point, reek of style and originality. You will probably not see anything else quite like this in a game again. I give the graphics an 8/10.
The sound is pretty good and fits nicely, but isn't exactly something you'll be humming after you power the PS2. I give the Sound an 7/10.
Now, something I'd like to point before I finish this review is the immersion and story. These two things, more than anything else in the game, is what truly makes this game so great. This is a buy, if you can find it.
