i like the way the wall-walk is always on, however, in corridors, especially the small corridors in pyramid for example, i don't like the fact that it's too easy to touch a wall and suddenly be at 90 degrees to what you were. i think if the wallwalk were kept the same, but some unassigned button toggled "auto-transition" on and off, rather than having to do it in the options menu i would prefer it. it would be a simple fix, since the option is already there, and anyone that likes the current system would just never need to press the button
