this is my invent, "imaginary clones" you think this might uses 2 sprites or a clone, BUT it doesn't uses not a single clone and only 1 sprite! this uses a list for x-axis, y-axis, size and costume, i am a genius! move the left one with a and d and the other on the right with left and right arrow keys
if you don't believe me enter to the code and there is not 2 sprites or a clone
