This Project on Scratch is really meant for 2-5 year olds learning the alphabet or to have some fun and find the kid in you by seeing which of the Characters (The Apple and the Green Circle) gets to Z first. Click Y and they will start at the same time, or if you want them to go separately than just click on whichever one you want to go. For whatever reason if you want or the Characters to go back to A just click on the Green Flag in the top right corner!
Just used motion blocks. Pretty easy.
