Hey! You're the second person to mention this bug, and I honestly have no idea what's causing that...

Please try downloading the game again using the Google Drive or Pixeldrain links... those are the official ones and have the fully revised and working version. Other links out there aren’t mine.
If you’re able to record a short video of the bug happening, that would really help me find the issue in the script... but no worries if you can’t!
Sorry for the trouble, and I really hope you enjoy Chapter 5!
