Click one of the characters to make their text box appear. If "Clickable" is equal to 0, you can't click anyone. Change the "Color" variable to change the box color. Give credit if you use it.
To use in a project: Change the text box costume to have the color you want. Make a costume in the "text" sprite for each of the lines a character will say. Make an icon for each of the characters, or for different emotions. Set the text to switch or fade away to make the character say multiple lines.
