Thanks so much for the feedback! I was wondering why sometimes you'd fall on the blue ice. Also good to know about the volume. Thanks again!
Good evening! I am making an addendum to my original comment. I finally figured out that the "mouse drifting right" problem only happens when I play Unity WebGL games that use cursor lock specifically on Firefox, and it does not happen on Chrome. It has nothing to do with your game specifically. I apologize for the misinformation.
