Press Space to switch shapes. IS THERE ANY SHAPE YOU WOULD LIKE TO SEE? COMMENT BELOW WITH SUGGESTIONS! Within reason please as I am no mathematician! Also, no curved edges. If you understand this, why not remix it with your own shapes?
See inside for explanation of workings. I have left in the original (now redundant) sprites as they are easier to explain and understand. Feel free to use with credit. Related project: https://scratch.mit.edu/projects/112362278/
