Super Atomic Boss is a single-screen shmup. It's just you, as a dinky little spaceship, against the boss, who is evidently both super and atomic.
You can move with the arrow keys and shoot with Z. When firing, your bullets automatically home in on the boss. But the point isn't to kill him; the point is to see how long you can survive.
The boss spews out totally random attack patterns: swirls of bullets one moment, expanding rings of bullets the next. You never know what you're going to encounter next.
Cleverly, one tool at your disposal is to not return fire. The game speeds up as you shoot, making it obviously more difficult to dodge; cease fire and it slows down again, giving you a period of relative relief.
What's your high score?
