When you say viewbob you mean camera bobbing right? Cuz if so, I sort of dislike camera bobbing and I know other people dislike it too, some say they get sick from it.
Having a toggle between regen health and non regen health would break the game a bit, since it's made with no regen in mind. Regen is a mechanic that I really dislike, it somewhat works for zombies but I still decided I didn't want it.
Any accessibility options are obviously still missing, as well as control remapping.
Having mod support for the game would be incredible, but the easiest way for anyone to mod would be downloading Unity, which would put off a lot of people. Making modding built in to the game would be rather difficult.
Thanks for sharing your opinion.
