Guy Fawkes first appeareance in a Spectrum game (correct me if I'm wrong).
The game's plot is to blow up the houses of parliament by collecting dynamite sticks and them blow them up at the right moment. The fireworks scattered around help you fight your enemies.
The game is very well designed with attention to detail, and the gameplay is straightforward and easy to understand what's going on, like with every JSW follower. So if you like hard challenges this is for you.
