note - this detects the last person to click button, not every person to click button. scratch doesn't let you do that without workarounds and i can't really use those supports numbers up to 100,000 (not a love/favorite detector) the way it works is when it detects that you've pressed the button, it updates a list with your username (safer bug-wise than just adding 1 to a variable). if you're already in the list, it doesn't do anything. when you reload and start up the project, it reads through the list and looks for your username. if it's there, then it identifies that you've pressed the button before and does whatever it does based on that. I mostly just made this because I've seen a lot of projects with rating systems and/or a heart thing inside the project. it seems sort of complicated but it's not really that difficult to create :I
