## Description

_Onefog Xonix_ is a variant of the arcade game QIX. On the playfield, enemy
balls bounce around. The player also controls a ball, which can move both
around the sides of the playfield, and inside it, leaving a trace behind.

When the player’s ball reaches the edge of the playfield, the area of the
drawn rectangle that does not contain enemy balls is filled in. If any enemy
balls hit the player or the trail, the player loses a life.
