The game - Spitfire - Atari 5200 | A5200

Spitfire is an action game published by Milton Bradley that was canceled prior to its release.

It looks like it was a Zaxxon-style game, but with the ability to move in any direction and the design in the style of "Crystal Castles". Alas, the game was just launched, but even now it looks decent, although it slows down.
