For Full Moon Sweet, we created a dialog box inspired by Oli414's Dialog Text Box Lib that could be used for both the intro story and the battles. All of the code for our dialog widget was pretty self-contained, so I thought I could package it up for others to use in their own games.
Z = Continue Text
X = Skip to the end of the line
The code for this could probably be made more efficient, so feel free to take a stab at it. Hit me up if you have any questions.
