So I have this bag so full of items that I can't put anything more into it. How do I get things OUT of the bag? How do I find out what is IN the bag? I have tried 'open' and 'look' without much luck. I'm thirsty...my water is IN THE DAMN BAG. Thx!
To look inside bags and other containers, type "look in <keyword>", where <keyword> describes the container. So try "look in bag".
To get something out of a container, use "get <thing> <container>". So per your example, "get bottle bag".
In the future we intend to implement a "natural language parser" which will let you type commands in ways which seem intuitive to you; and it'll mostly figure them out. So you could say "get the stinking water out of the damn bag", and it would. Not sure how much of a priority to make that, will have to wait and see what kind of feedback we receive. Might be better to invest in building the game world right now. Dunno!
