Might play a bit like Xevious, no?
From what I can recall, the screen didn't scroll automatically. You had to move it upwards yourself. And I think you moved pretty slowly. Moving would decrease your fuel, and as far as I could tell, there wasn't a way to replenish it, so a game would just end after a couple minutes. The only enemies were those swastikas, which I think just moved side to side and shot at you. The gameplay wasn't particularly exciting, but it was hardly the worst thing on the console, and given how terrain didn't do anything and the strangeness of fuel without an ability to refill, I'm thinking that what we have is rather incomplete.
Of course, I haven't played this thing in over a decade, so I could be misremembering something. Feel free to correct me on any of that CPUWIZ.
