The game is simple, there are two players with a chalk and the chalk never stops moving, it keeps moving in a constant speed. The only control the players have over the chalk are its direction. Player 1, who controls the blue chalk, turns the direction with the up and down arrows. Player 2, who controls the red chalk, turns it with the keys: 'a' and 'd'.
This project is not entirely pen, the only pen part is the chalk. This project was made kinda quickly, within 1 hour. And I was inspired by Curve Fever.
