Sorry I was too blind, thank letting me know lmao. I tried it but it seems to affect the NPC way more than the playable character, I'm not sure of it's intended. Also running footsteps SFX are quieter than walking ones (that have a good volume imo)
Also I forgot to add, a colour changer for eyebrows or making match the hair colour would be nice, they stay blonde so it's weird if we use different colours.
