So, here it is! This is my pre-drawn stickman made with this tool. To draw, remix this, unattach the drawing script and the green flag block. After that, attach the space key script together. Press space to draw, and make sure that your drawing touches the Scratch Cat. Note that the limit is 200000 (Scratch limited it)! When done, make it the original and DO NOT PRESS GREEN FLAG BEFORE DOING THIS. After doing this, press green flag. It should work!
Made by me (P.S. When having it draw, use turbo mode to make it faster! You could do so by pressing shift while hovering the mouse into the green flag button.)
