****IMPORTANT**** THE TIMING IS ALMOST GUARANTEED TO BE INCORRECT NO MATTER WHAT YOU DO. I have made a video that is very close to this one but with the correct timing. Please watch this instead! https://youtu.be/tYs0dHR_TB4 (If you can watch the video, you can ignore all of this below.) If for whatever reason you can't watch the above video, I think it should perform better if you download it! However, even then, you may have to watch it again after the first time for the lag to go away. And if for some reason you can't download it either, the next best option is to: -Click the green flag twice -The timing may be off the first time you watch it! Just try starting the project over again after it's finished (without refreshing the page! Just click the green flag twice again. xD) and it may be better. -It honestly just depends on how your computer plays it. Your computer is probably just going to play this project differently every single time, lol... It's not very consistent, unfortunately. It's seriously just best and easiest to watch the video linked above.
