arrow keys, space when done. don't go near the edge if you want your snowflake to be symmetrical. (there's no fixing that bug, the problem is Scratch not the code) Also my profile pic is from this
I basically copied this from another project I made, added the down arrow, made it 6 sides instead of 8, and blue instead of rainbow. My credit for the other one was a coding book I have that has basically the same thing as the other project but I modified it because in the book it was just annoying.
