You can only chat to yourself, and it doesn't use cloud variables, so New Scratches can use it too. Click the green flag twice to avoid glitches. Use full screen mode to see the dismiss button. It takes a bit for the chat to show your message. (Longer message -> Longer wait) Use this project if you want this type of chat in your project! If your message is too long, it won't load. Have fun! And tell me any bugs.
