A diamond in the rough.
The story and dialog is forgettable, and at times a bit stupid, but at least the game play helps you get past that.
There may be times when you don't know where to go, or what to do, you may need to back track a lot. But it is fun and enjoyable.
It's not that hard of a game, but the first time through you may die a few times. Afterward you know where all the hazards, and enemies are, and what to do.
If you can find a copy I suggest you check it out. I got my copy for pretty cheap, so more than likely you can get yours for no more than six bucks.
I recommend it, check it out.
