You know what? I actually remember thinking "this reminds me of Clem's house from The Walking Dead" when I was inside, seeing that view of the kitchen and sliding door. I never noticed it was the same one with the treehouse or I'd have gone nuts!
Definitely not a co-incidence with those pic comparisons; the tree house is the giveaway.
Kudos to ND for tipping their hat to another amazing game like that.
