Press p to pause and space or w to jump leave favourite and star pls. Press z and m while in game so the game stops and if u click u can build on the map. The press z and m again so it will start. if u want it to be slower and to change ur costume press J press H to be normal again(but slow), u gotta restart to be normal again it will still have ur edits until u restart scratch or close and re-open the project
