MazeFinger is a fast paced reaction game from ng:moco, the new iPhone OS game development company founded by EA alum Neil Young.
When each level starts you are presented with a maze that you have to drag your finger through as quick as possible to reach the goal. Seems simple, and the basic idea is, but there are some great obstacles that can show up and other interesting twists that keeps it interesting.
Your speed through each level is graded and you can only continue as long as you have power -- the quicker you finish a level the less power you lose. There are 5 boards to each level and your power is refilled at the top of each level.
There are a couple things missing from this game. Game saving and global high scores. And there are some bugs, looks like it might have been rushed out the door a little too quickly. But it's free, and it shows great promise.
While I haven't gotten through all of the 1000 levels in MazeFinger, I have gotten through quite a few. It's a great little free game, grab it.
