Hi! To use Sketchpad, you simply use your mouse to draw ( or use your finger for mobile ) and the up and down keys for changing the size of the pen ( still working on that for mobile). Space key for erasing. THANKS FOR USING Sketchpad!!!
This is a work in progress so if you want me to add something then pls let me know. I am working on adding colors and a more mobile friendly version so please be patient, it might take me a while.
