The weird is, I connected my headphones and upped the volume to the max, and I got even quieter sound. xD
Thanks for the consideration anyways. Maybe a volume slider at the beginning of the game could help with that.
Some of the audio in the game is based on your position in the level. If the audio gets quieter, it could be the narrator moving away or you moving away from the narrator. If this isn't the problem, we apologize for the inconvenience.
Regardless, we'll make sure to put in a volume slider in a future version. Thank you for your feedback once again!
