Bit late and you seem you found the answer anyway, but: Deepness at this state surly isnt given, but this would be crazy given how long both sibling-parents are around.
Mechanical its on pair (not without nitpicking ofc, imho its really silly that something like a scratch dosnt heals of itself and, as stated in my OP, im on war with the seedsystem), and I would say that menu navigation is a lot more intuitive than at least unreal world (what, frankly isnt that hard tho. My only struggles so far are me problems like apparently no longer seeing "or" and "and" in recipes if not color-coded).
Aside vom my NASA-level struggle of finding water, I think many of my issues (as in, lack of recipes/alternatives. Hunting for a dead tree everytime the character oversleept the, very cool, chance to rekindle the campfire is for example really annoying) will be resolved in a few months.
