Well, a message spelling out "Secret Message" Appears on this blurb. You might be thinking, DUH! Just have a text sprite hidden then show! Right? Well, there is one sprite, one costume, and one script. Don't believe me? Go check. Comment if you know the answer to... THE SECRET MESSAGE! (When you find out, you will feel so dumb XD)
I give the credits of this awesome new messaging technology to myself.
