| In the Famicom manual, a round climbs from the first floor to the fifth, where Sylvia is held, and rescuing her moves the game on to the next round. Each floor has its own timer, and Thomas must beat the enemies and climb the stairs within the time. Some enemies fall to one hit, some to two, and some only when their energy runs out. Losing all his energy, or running out of time, counts as a miss. | PDF p. 10 (printed p. 8), rules and techniquePDF p. 10 (printed p. 8), rules and techniquePDF p. 10 (printed p. 8), rules and techniquePDF p. 10 (printed p. 8), rules and techniquePDF p. 10 (printed p. 8), rules and techniquePDF p. 11 (printed p. 9), missPDF p. 11 (printed p. 9), miss | Manual |
