The plot of Mark of the Ninja is straightforward and uncomplicated. It's nothing special, but ultimately it serves its purpose and contributes to the overall experience. It's a well written story, and it works really well with the game.

Personally this is one of the least important areas of any game for me. I often play games without the sound. However this may not be the case for everyone. Klei Entertainment did a good job of picking the sounds for various actions in the game. The sounds provide audio cues that reinforce what's happening on screen. For example, if a guard notices you there a sound as well as visual cues on screen. The soundtrack is also good. It fits with the overall theme of the game, and isn't overly intrusive. Additionally the voice acting is superb.
This is perhaps one of my favourite parts of the game. Mark of the Ninja really shines is the visual department. The stylistic choices and art of the game are stunning. The particular cartoon art style especially appeals to me. From the distant background, to foreground, the quality of the visuals is always impressive and never excessive. The animations are smooth, entertaining, and aesthetically pleasing.
Mark of the Ninja is exceptionally well designed. A stealth puzzle platformer the attention to detail really comes through. The game is consistently varied, which keeps it always entertaining. The puzzles and difficulty is perfectly attuned so the game always presents a challenge, but is never unnecessarily difficult or easy. Furthermore the variety and various unlockable items in the game greatly increase the replayability. It is important to note that replaying the game with different/ more items is genuinely entertaining, not just an add-on to lengthen the game.
