Solid shooter with nice graphics, sound effects, and a feel like I'm playing an arcade cabinet. Not sure I really grasp the "want to stay smaller" concept as the powerups gives me such as boost that I found it easy to win. Idea is there but perhaps the powerups should also affect speed, handling, firing rate, etc. all to make it more evident that "Sure, you are a tank but you are also a much easier target to hit now and will soon lose because there's too many of them and you are not fast enough to get them all" :)
