Yosaku to Donbei (c) 1979 Wing.
In this title you play a little farmer guy, who is attempting to shoot down the crows out of his tree. Gameplay is identical to that of 'Space Invaders'. A large bird replaces the UFO that goes over the top of the screen from time to time. While a lumberjack will chop out a section of the tree every time the birds reach the side of the screen (lowering them closer to the bottom). The only real gameplay difference is that the birds come in a pyramid pattern, as opposed to the rectangle pattern of 'Space Invaders'. This serves to make the game much easier.
