use the sliders to change the variables that do stuff to your trail. (trail size changes size, trail brightness changes brightness, trail color changes color, trail shape changes the shape and the special makes it rainbow) also use space to change the background
this was inspired by "make a mouse trail!" by amazinggirlonpoint12 on the front page of scratch also a link https://scratch.mit.edu/projects/466656063/ and also I did this all by myself without pen
