mm.. think the screen is a bit to width for a vertical-Shooter
Every shooter i know has a screen size like the shooter itself.
Verticals have higher, thinner screens
Horizontals have wider and lower Screens

In your video, it looks static because that little ship flies on a BIG Screen, with a nearly static background

But that´s all your thing ^^ just my point of view. I like the smooth run with that many objects, and the graphic isn´t the worst. go on with it ^^
