Black Hole is a fixed-screen shooting game published by Tokyo Denshi Sekkei in 1981: you must systematically destroy the screen's terrain, cross point-ships for bonus, and only then face a moving figure that crowns each level, all while dodging mines that split apart when hit.
It's a title typical of that experimental moment before the vertical shoot 'em up genre fully standardized, with a structure closer to a terrain-destruction puzzle than to the bullet-dodging that would define the next generation of shooters.
