Thank you so much ^-^ If you were playing one of the video versions, then it’s pretty common, sadly >.< I don’t know exactly what was causing it to happen, but there was a conflict with the video sprites and the voice acting that caused the game to lock up if the text was advanced before it had finished printing or if the text was advanced before a voice line had fully finished playing :( You could temporarily fix it by rewinding 1 line of text in most cases, but it would still keep happening throughout the course of the game >.< In the end, I just decided to scrap the video versions, haha. They might’ve looked pretty, but they were more trouble than they were worth, sadly.
If you experienced the freeze in one of the potato versions though that only has pngs for images, I don’t know what on earth could have caused that T_T
