iPhone developer Lazrhog has posted about a YouTube video of his upcoming game rRootage. rRootage is an iPhone port of the the shoot'em up game originally by Kenta Cho. The version shown in the video is the same one that was submitted to the App Store.
The game involves constantly firing against the enemy mothership while avoiding wave after wave of attack. The ship is controlled by your finger and a sheilf can be invoked by tapping with another finger.
The game will be available soon for free and is currently under App Store review.
