There's a bug on the page showing the results of singing September during karaoke. Samantha's first dialog line is missing an @ in the script. That causes her line to be printed in white with other script formatting coming through and the narration afterward is formatted in yellow. After that, all dialog on that page is in white and narration in yellow.
The bug does not persist continuing to the next page. The bug can be replicated in the download version, the one embedded in the Itch store page, and the one hosted on amaty.space.
