If possible, please add the ability to toggle walking speed. I found the beginning section a little awkward to have to jog through during some slow parts when I just wanted to look at stuff.
Additionally, adding in secondary keybindings would be great. So, being able to press R or another set key to reload, for example.
This would be awsome for people that want to roleplay or just take some parts slowly as you said. Something like in WoW to press / and just start walking no running.
