Can you please describe the bug you are having? I am not finding anything would be causing a freeze.
A strange bug indeed, I think the fairy is getting stuck as she is supposed to move to the left. I've uploaded a fix you can download. Unzip the www folder inside the new download titled "Ralphs Myth Fairy Fix" to your game's folder and it should work as intended.
I do not know if a saved game inside of the room will work. If you encounter any issues, you can send me your save file and I can fix the issue if it has persisted.
I appreciate your time playing my game and noting the issue.
