Zombies

Description
Zombies is a 1-player arcade game for the BBC Micro.
The player is on a screen filled with zombies and an equal number of zombie-killing squares. The zombies move straight towards the player, and the player must lure them onto a zombie killing square. If the player is touched by a zombie it's game over.
Zombies speed up as time passes on a level. After killing all zombies, the player enters a new level with one additional zombie.
