Extermination of rats

The player can operate with the joystick on the left side of the screen, and move the viewpoint with the right side of the screen. Also on the right side of the screen there is a gun fire button and a jump button. The stage is like a small town, with enemy rats running around attacking you. If you hit it, your HP will decrease. The game is over when the HP bar in the upper left becomes zero or the time is up, and the game is cleared when the HP bar of the enemy in the upper right becomes zero within the time.
