They remade and cut content so many times, I don't even know
Town is way different, there's a forest, the field might have been a larger area, Sammy's room is different, there's 2 big puzzles we never got, Sammy's robot roommate, https://www.youtube.com/watch?v=IKvDypy1Mrw
This has Sammy's roommate so they developed that more before scrapping it. It also has running from the mech guy and a scene where Alex is on his back?https://www.youtube.com/watch?v=X5vUb3C9GcI
This one has an Essentia puzzle with krow nearby?https://www.youtube.com/watch?v=gpFXydY1K8k
