Simply press the green flag and try to make sure that the ball doesn't touch the red line. If it does, then the game will stop. To restart, press the green flag. Also just move your cursor. You don't need to drag the green line. Have fun!
Thanks to Scratch NOTE: If you want to remix, please ask me :) And also I have a studio named ♡RainbowSquad♡ so you can follow it if you want. I just mostly add projects, chat, and have fun. Join the ♡RainbowSquad♡ today! Here is the link: https://scratch.mit.edu/studios/31667280/
