Also, there are some music segments that seem out of place. The thing that I was most critical of in terms of audio is that your character's footsteps are too loud. Even though you are advised that it is sometimes better to avoid soldiers rather than fight, they invariably hear your footfalls and come running. I was enthusiastic about the option of taking a stealthy, Thief -like approach but found it frustrating that I was not able to sneak past the guards. Stealth is sometimes preferable to force, but not easy to accomplish.
Level design is above average.
I felt there was some definite similarity in a number of the levels, particularly in the catacombs. The developers have worked diligently to throw in some curves, however, holding your interest through the level. Puzzles are typical of the genre and not altogether too challenging. Explore a bit more and, lo and behold, you'll come across a key lying about. Other perennial favorites include buttons to push, switches to flip, valves to turn, etc.
