Demons to Diamonds

Demons to Diamonds is a game released for the Atari 2600. It was developed primarily as a children's game.

Gameplay
You and another player have joined a Cosmic Carnival shooting range match where you must carefully target demons the same color as your laser cannon. Blast the right color demons and a diamond will appear which you can blast for bigger points. Blast the wrong color demon and he turns into a skull that you cannot destroy but constantly fires shots in both directions. Sometimes skulls will appear out of nowhere just to give you trouble. As you proceed from wave to wave, the demons move faster and the skulls start moving.
