There are three ways to get contrast.
Way 1: Get it from github, go to github.com/Pygasm/Contrast and download the game, then read the instructions on "run.txt"
Way 2: Get it from my pyweek entry, click on my main entry, and click on "Contrast.zip", and read run.txt after extracting.
Way 3: Get it from my domain (Not done, will add later)
If run.txt is not included, here are the instructions
1. Install python 3.6.x
2. Run this command to install pygame, py -m pip install pygame
3. Open "Contrast.py"
