Press the flag, watch me draw Iggy, then hit space. Move the mouse around. click to draw. when your drawing is complete, press space to see the pen perfectly recreate your drawing! while the recreation is going or at the end of it, press space again to make a new drawing. press the right arrow instead to continue work on the original drawing.
I accidentally hit create then thought- why not try to make something that recreates what you just did? Inspiration for that idea came from the game Help Yourself, it's in my favorites. So here is a project where you can draw something then flawlessly recreate it by pressing space. It's awesome! And relatively simple to code too, using only one sprite with four scripts, one of which is a custom block and another just quickly broadcasting something when you hit the flag, so really two main scripts.
