Uh, there are quite a lot of keys to press. I have included it in the project but I'm gonna say it once more here. Arrow keys to paint, WASD to change colors, 1 for making line thinner and 2 for opposite, Space for stop drawing lines and b for opposite, c for clearing your canvas, n for ending your master piece, m for changing to black canvas & v for the opposite.
Yay!!! Uh, I just made this project up when I tried to discover the pen stuff. Then, I found that this is a classic. Hope you enjoy!!!
