I recently picked up Silent Swords by Oniric Games and I must say that it is an attractive game. The game puts you in the role of a ninja that has been captured by a military organization. Your mission is to get out of the complex using all the ninja skills available to you.
The saccharine graphics may make the game seem childish and simple, but you will definitely need to use your brain to get past the guards. Silent Swords has a nice blend of nice graphics, strategy, and realism, and seems like a cross between Metal Gear Solid, ninjas, and a platforming and puzzler game. Though the concept may sound a little weird, the game is definitely worth considering.
