Zmija

## Description

_Zmija_ is an adaptation of a _Snake_ game. The player controls a snake using
arrow keys to make it move in one of the four directions, left, right, up or
down. The goal is to eat all the stars on the screen without bumping into
anything else which makes the player loose one life. The game start with 7
lives and clearing each screen and going to next level grants additional life.
There are seven different screens in total which vary in difficulty by having
more obstacles. The snake itself leaves a zero behind after eating a star
which adds one more obstacle on the screen. After beating all new screens, the
game starts from the first level again but at an increased speed.
