Really great graphics for a shoot 'em up that's as simple as this. The effects, ships and the background all look very nice and detailed. The gameplay is fine too with the four-way movement and great power-ups. The only complaint I have is with the aspect ratio and how close the camera is. Usually shoot 'em ups have more vertical space to give the player more distance to the enemy ships that appear on the screen.
I'd like to invite this game to take part in our Game Development World Championship!
