Don't press the button as soon as it appears, because it kind of ruins the text. I did it to check my thumbnail, and the text kept playing, and I had no idea how to fix it, so DON'T PRESS IT IN 2 SECONDS. Also, fullscreen recommended.
It took me around 2 hours to make this. I had a lot of errors to correct! Also, I accidentally deleted my 'redbutton' sprite, so obviously, all the code deleted too, which stunk, because there was a lot. But I fixed it.
