Quantized Blaze is another excellent shmup from acclaimed developer keim, responsible for releasing both Nomltest FS and Sky Swimmers' Heaven. Like most of his efforts, the ship's cockpit is the actual hit point which you must protect at any cost.
Bullet patterns are programmed, and enemy formations hardly change much if ever at all. You lose a life automatically when a blaze crosses the bottom of the screen, which can be prevented by using a bomb.
Keyboard controls are not advised, because you need decent bullet dodging skills to sign up for this shooter. Press the left shift key to shoot and launch a bomb using the Z key.
