## Description
_Tommy’s Gorilla Ball Ramparts_ is a single-player DOS game. The player takes
on the role of the defender of a castle. They can move left or right along the
top of the screen. Along the bottom of the screen are enemies who are trying
to storm the castle. They move left or right and at random points they erect
ladders to scale the castle walls and they can also shoot arrows.
The player defends the castle by dropping cannon balls onto their enemies and
by cutting the ladders they erect. Arrows can be dodged or deflected by a
shield. Any enemies who make it to the top of the wall must be killed before
they have chance to fire an arrow and kill the player’s character. The game
has nine levels of difficulty and records the top ten scores for each
difficulty level.
