Well in this game, there was the chair (see my other comment) that no human would sit in.
There are other tells that process that doesn't understand the continuity of solid objects created the game, not a person.

• You can walk through most of the walls and half of the scenery. Walls don't normally work like that.
• The explorer skeleton in the twisty maze room simply is not there. He should be sitting beside the key that's nearly fukin impossible to find because there's no skeleton next to it, despite the room description saying he's there.
• The paddle for the inflatable raft is in two pieces, the blade sits about a foot from the shaft it should be attached to.
• The diamond mill output is ... nothing. It's just a spot on the floor, uncomfortably far away and disconnected from the mill.
• The area where you have to deal with coal gas is just a complete fail, the AI did not understand and just made some crap.

.
There were two other questionable bits where I don't remember the original game, but it seems the AI flubbed. The 4 button dam controls were wonky: stop, start, bust the pipe, and what? And the cyclops room has a door you never get to open, no info about it.
All together, these seem like things no human would get wrong. Like, maybe a human would make a shitty chair, but they would almost certainly ensure that all the pieces fit together before they published the game.
