You've heard it many times, but this game really is like an interactive crime novel. And it's loads of fun
What is so freaking cool about this game is the way that it incorporates touch-screen gameplay. So many DS games out there that are centered around the touch screen seem flawed or gimicky in some way, but Hotel Dusk gets it right by keeping everything varied and thought-provoking. Many of the actions that your character must make are acted out on the touch screen, such as using a crowbar to lift a cabinet, solving match-stick puzzles and various "detective" actions. It also goes back to the depth of the story line, since you will need to stay keen on everything that has happened in the game in order to remember where you should go and what you should do. You really feel like a detective, and that your choices are important and have a direct effect on your progression through the game.
If you've read other reviews for Hotel Dusk, you have undoubtedly been told that the unique visual style is very cool and atmospheric, and this is the absolute truth. The backgrounds are all 3-dimensional and realistic (for a DS game, at least), but the character models look like they were scribbled in with pencil. It sounds primitive, but it fits the style of the game very well and adds to the mystique. In fact, I think it would have been a huge mistake had the developers made the character models in the same style as the background, since it would have detracted greatly from the game's originality and appeal. The music is also well done. It stays fairly subtle throughout, but kicks up a bit in big situations, such as during a high pressure interrogation. In every facet of the game, Hotel Dusk excels and creates an overall experience that is my favorite game for the DS so far.
