Ngmoco has released two of its new games for the iPhone and iPod Touch in the App Store. First title is Topple, available for just $0.99. In this game you need to stack weird shapes using the multi-touch controls to slide and rotate them into the position you want them to be. The second title is MazeFinger, a free maze puzzle game with more than a thousand unique mazes that you navigate by using your finger on the screen of your iPod Touch or iPhone. Every maze has hidden traps and other things that might get in your way. By playing through the 200 levels you can unlock new achievements.
