Hrmm interesting. The portal sound should be -10dB of the maximum system output so they are relatively loud and there are box sounds (when the box's rigidbody is above a certain relative velocity; the sound is 3D because it would be out of place as a 2D sound). I guess the footstep sounds could be more interesting. There aren't too many things visually in the game that could produce sound so unless I add in random sounds for things that aren't on screen, everything has a sound. I guess it could sound plain because there aren't a variety of visual sound sources so there aren't that many total sounds that could be played
. Again, thanks for the feedback!
