I used a "score" variable that changes by 0.5 every 0.5 seconds. Then I added a cloud high-score and did all that coding. Finally I added a variable called Score/High-score and used the Join(xxx)(xxx) block to add the score and the high-score in one variable. You can see inside if you are confused.
