*Snap* is my new favorite verb.
(Graphics) I happen to like the graphics - attention to detail, but not so blaringly huge as to detract from the gameplay.
(Style) Awesome game, the walltapping is what gives you a 10 here - whistling is so cliche and whatnot. Walltapping requires the added intellect to find a close wall and *tap* wait *snap*.
(Sound) Any sound that doesn't detract from the playing is perfect 10 in my book, and for the most part, I found the mood to be set by the music perfectly.
(Violence) *snap* Need I say more? Okay, then give me more guards to kill. *snap snap snappity snap*
(Interactivity) This game actually has multiple ways to beat levels - mine is, by far, to get close, walltap, and *snap* anyone who comes to investigate. Perfection.
(Humor) No real humor, but in games like this, you get what you take, and I happen to be takin' lives. And the first time I heard the sound of three guards' necks snapping in a row, I fell out of the seat. (And almost got caught by the fourth guard.)
(Overall) Take a little Splinter Cell, remove the guns, and tweak to perfection over a low heat. Marvelous.
Oh, and Andrew, NEVER, EVER insult a game with the "I could design better" when you don't have a single game that has gotten past the blam screening process. Come back after you make a few decent games, and maybe you'll have a valuable opinion.
