Setting aside my disappointment in the delay for Kimi o Aogi Otome wa Hime ni (See Sol Press - Blog - Update on the Status of My Fair Princess), what actually constitutes a major bug in a VN. I mean, for the most part, they are a bunch of text and pictures presented in sequential order with a few if/then/else statements to branch the story line. I can see somebody screwing up the initial setup of the if/then/else statements, or getting the text/audio/visual components out of sync, but how hard is it to go back and correct those errors once you become aware of them?
