I spent an hour and half on trying to figure out what to do ending up reading StealthC comment. I know how frustrating if someone can't figure out what to do in your game, I have this one everytime, But systems you implemented in a game are great and it takes effort to do it right and you did a great job. One thing which keeps getting on my way is highlighting every object in certain proximity to player, it will be good to have only one to interact with. Keep it up a good job thank you.
