This was a successful test. This is a 100% pen snake, no clones, just pen. And it has only 1 forever loop, so there's not much lag. ---- Use Turbo Mode! (shift + green flag) --------- Turbo Mode is needed because I have repeat loops inside the forever loops, and Turbo Mode deletes most of the delay between the loops. --- Did you know? --------------------------------------- This actually doesn't "erase" any pen. What this does is it renders the snake super fast, and if you turn off Turbo Mode you can see it rendering.
