Gradius V - 54 by Shinya

In Battle City, your goal is to destroy enemy tanks while trying to keep them away from your base. Each level includes 20 enemies as well as some obstacles, like the weak red bricks, armored silver bricks, water and ice, which you can use to your advantage. The basic tank you start with can also be powered up little by little throughout the game. In this run, N?K rolls through the game speedily while losing a little bit of time to entertain with amusing shooting patterns and making the scenery into recognizable letters and shapes. Spoiler: Hover over the screenshot.
