This is a doujin shooter that feels very unfinished. There's no demo screen or main title, the game just starts. There's a fair amount of flicker, and no real game over screen either... it just boots you out to the DOS prompt. Arrow keys move your ship, Z and X shoot and use bombs. The play screen is relatively small given your large ship, and enemies have a tendency to come in from the bottom at high speeds later on, and your respawn invulnerability is really short.
