I gave a game another shot to actually check how wrong I am and I would like to clarify my original issues with sounds. It seems for after playing on risky-loud volume and with concentration that game does not position sound effects depending on monster position to the camera (left/right), or it does so very very very poorly (I am not entirely sure cause some sfx are definitely stereo).
I just don't get it. Game has strict 90 degrees rotations and when monster is coming from the left (I sat a lot in the beginning where there's probably definitely only one of them) I just hear sound in the center. I mean I do hear that some sfx are stereo, but they are not positioned in space. Maybe it was an oversight in the development, like enabling 2d/3d property for the sound emitter? (i'm not familiar with it is done in godot).
