Green Flag. Click anywhere. Type in a number at the cursor (then press enter, or click somewhere else, or drag the numbers you typed somewhere) Type as many multi-digit numbers as you want. Drag any of the numbers to other places on the screen.
Same principle will work for any character. I've only implemented digits as a demo. Could also work for multi-part sprites (eg a body with a separate head, arms, legs etc) 300 digits on screen maximum due to clone limit. Does not implement delete. Or minus. Or decimal point.
