As in the movie, your goal is to rid New York city of the invading gremlins. Armed with a flashlight, you will track down the little monsters through many Big Apple locales, each with its own challenges and hidden surprises. The gremlins attack you by rolling themselves up like a cannonball, in droves at a time. This makes the game very challenging even for joystick experts, as it is often impossible to dodge or jump over the rolling gremlins. Fortunately, you can find extra lives to add to the seven you start out with.. but it takes a very observant gamer to find all the hidden bonuses. Overall, a fun game that's worthwhile for fans of the movie, although the addition of cutscenes between levels would have made it a much better game. The game is also notable for being the very last game developed by famous Spanish developer Topo Soft.
