Thank you very much for your feedback. Yes there are many things that aren't supposed to be the way they got in the end. I ran out of time because I started 1 or 2 weeks late and I put a bit to much time into animations.
Yeah I didn't have anymore time to actually say what those different "interacting spots" do or which requirements have to be met to get them work. For example you need to find a can of fuel and than fill up a generator. After you have done that the elevators will work. Next time I will at first make sure that the game and all its mechanics can be understand before diving further into other stuff.
