For me a true 100% pen game is a game with absolutely no costumes other than a single empty box for offscreen rendering (Even this can be avoided with set size to 1/0), 1 single sprite and no background costumes either. All graphics need to be rendered with pen including polish such as a starting menu, ui and effects. Stamping sprites is not allowed in 100% pen. These are the main rules. If you want extra complexity: - No clones. (Use lists instead) A example that follows all of these rules is https://scratch.mit.edu/projects/1215116389/ .
