In the middle of winter a turtle is defending his strawberry patch against a variety of marauding bugs. Some go for strawberries, some go for the turtle. The turtle, for his protection, is armed with a gun - one, not two as the title might suggest, but that doesn't make any difference to this very fast game. Bugs stealing strawberries, pick them up and sidle off screen, but if they are shot, then the strawberry drifts back to its place.
The game is played out against a calendar starting in October. As each month passes, the type bug changes. It's already snowing slightly, but as winer nears, larger snowflakes fall and these may be picked up for bonus points.
The strawberries, twelve in all, float in a neat three by four block at the centre of a black screen. In the background pixel drops of snow fall. The monsters float in from both sides and the turtle may move all over the screen shooting in the direction of movement, but only horizontally, although he can move in eight directions.
