Someone please help, this is driving me absolutely crazy.
It was an old PC game, not played online, in the 1990s. It has a completely black background and a shape (simple line drawing), depending on the level, in the middle of the screen. The shape would get narrower almost as if it was disappearing into space. You were a bracket looking thing at the edge of the shape and could control where you were using arrow keys. Things would appear far away inside the shape and you would have to move around the shape outline to shoot them (I’m pretty sure with the space bar). Each level higher the shape would get more complex with more sides. I would consider this a 2D game. WHAT IS THIS GAME??
