There's quite a bit to the mechanics.
The only one that I couldn't find many uses for was the stealth crouch.
There's a bit of an annoying bug where enemies clip into you.
And one time I confused the spawning campfire with the end level camp fire.
Other than that, pretty great.
I'll post my playthrough when it's up.
