## Description
_Zaptrak_ is a variant of a snake game. The player controls a man who leaves
a trail of wall behind him as he runs around the screen. Running into the
trail or any wall has to be avoided since it costs a life. The aim of the game
is to increase the man’s energy level which is done by running over electrical
discharges (displayed as yellow squares). The player has an energy level of
100 when starting out and it decreases quickly when standing still but is
stable when moving around. Running over the discharges increases the energy
and upon reaching a level of 500 a door opens at the top of the screen which
the player has reach to end the level. In addition to the discharges there are
also pink obstacles that should be avoided since they force the player to
stand still for a short while and therefore decreases some of the energy.
There are four different stages in the game. The first one lacks obstacles
more than the outer walls and has the yellow and pink squares appearing at
random. The second stage features a spider that move in lines from the top to
the bottom and leaves squares in its path. The spider has to be avoided since
it will kill the player upon contact. The second stage also adds obstacles
around the screen that also has to be avoided. The third stage is like the
first but with obstacles added and yellow squares appearing less frequently.
The final stage is like the second with a spider moving around and laying
squares but here it moves in multiple directions and is therefore harder to
avoid.
