Use arrow keys. If you remix, you can add levels with this process: 1: press “see inside”. 2: go to costume editor. 3: go to whatever the last “level” costume is. 4: right click on it. 5: click “duplicate”. 6: erase what you don’t want. 7: add what you do want. IMPORTANT! Do NOT change any costume names, or the entire thing will probably stop working.
