Both the combat and puzzles are fairly easy. What might make you a little tense is that with limited ammo and items you can die near the end of a level and be forced to play the entire area over again. However, Dementium has a lot of charm. The graphics and sound are excellent and despite the story's lack of originality its creepy atmosphere is a great achievement for the little handheld. Put your earphones in and play the game on the back seat of the bus on the way home from work for chills and spills.
