Just my second pen creation. Right arrow to increase pen size and left arrow to decrease pen size. W and D to change backdrop color. Space to erase all. It doesn't work in turbo mode. Hold down arrow to pause. S for pen down.
It looks weird in turbo mode. FOR ADVERTISERS: GO TO THIS LINK FOR MY APPROVAL: https://scratch.mit.edu/studios/27095146/projects/ Tip: 1. Switch to turbo mode. 2. Press right arrow. 3. Hold left arrow for 1.5 seconds.
